What to pick for my next pair of classic skis?
Zach, Nathan, Eli, et al:
Over the past two years, I've fallen back in love with classic technique, and made pretty serious improvements in my technique. I bought a new pair of Fischer 812s last year hoping that they would become my 'A' skis (supplementing my 8 yo ARCs). Both pair were flexed by Tom Novak and Ahvo to make sure they did fit. So... The 812s seem to work very well, most of the time, on manmade and firm natural tracks. They do require pretty significant kick to get them to bite - I found I was often one wax warmer than others to get reliable kick. The kick zone was very well defined, removing any kickwax outside the pocket in about 5K. But they are rockets on glide, so I felt pretty good about getting them. The Atomics have been Buicks -no flash, not extremely fast, but pretty reliable (but getting to where I doubt Tom can grind them more than once more). When it came time to pick skis for the Birkie, Ahvo suggested them instead of the 'faster' 812s, suggesting that the softer kick would get me to the finish line better. He was right. I had kick all the way, getting out of the tracks only a couple of very short segments - and mostly for traffic. And skied a PR, in spite of having my skis disappear at the start and missing my wave by 10+ min. So the question of the day is: In general, what would you add to a classic quiver for next season? A pair of 'wet' skis, or a pair of hardpack skis with a little softer pocket that the 812s' WC one? TIA, Marsh Jones |

What did your 812's flex at? How much do you weigh? What conditions do you
ski/race in mostly? If you don't know flex numbers, what flex are the skis (soft, med, stiff) and what length? The hardest part to figure out is your technical proficiency. This can alter the ski selection significantly. It sounds like you're a strong classical skier, but how long have you skied, what kind of coaching have you had, etc? -Nathan www.nsavage.com "Marsh Jones" wrote in message ...

Hi Nathan, 46.7, 195 dropping to 190, turn 50 this summer. Minnesota conditions... Med flex, 207 Cold. The hardest part to figure out is your technical proficiency. This can alter the ski selection significantly. It sounds like you're a strong classical skier, but how long have you skied, what kind of coaching have you had, etc? Hard to say. The only two serious races last year were Mora, MN (20s,orange klister, 812s) and the Birkie (3:16 watch time!) (single digits, VR40, ARCs). OK, the rest of the dirt. I've been skiing since the mid-70s, off&on. I started trying to classic seriously again 2 years ago, race canoes in the summertime, and have had minimal formal coaching - a couple of sessions at local clinics with club level coaches and a fair amount of critique from my highschool team coaching partner. If time works out this year, I'll participate in Finn-Sisu's program. If not, whatever seminars I can fit in. Technically, I'm so-so. I slap badly at times, don't get enough drive out of my arms, don't explode off the ski when I get tired, but I mostly can keep my back curved and keep my head down.

I would pick a softer pair of 812 plus. It sounds like the 812's you have
seem a bit on the stiff side, given those flex numbers and your experience with them. It sounds like they are good in hard track conditions and for klister. My softest 812's that I find great in powder are 34kg (I weigh 71) - 48%. My klister skis are in the 41-42 range (~58%) with a camber height greater than 1.1. I think a good "universal" powder ski would be something in the neighborhood of 50-52% body weight with a camber height of 0.8-0.9mm. But then again, I don't ski on Minnesota conditions that often.

Hi Marsh - Sounds like you've got some really good advice from Nathan.
I'll see what I can add to what he's said: It sounds as though Tom and Ahvo did a good job fitting you. The deal with the 812 is that the pocket is particularly position-sensitive - especially in the 202 or 207 lengths which are really designed for an aggressive world-cup style male skier. The 192 and 197 are set-up as "women's" skis and are more accomodating of a somewhat more neutral body position. To clarify things a bit - the 812 wax pocket is typically positioned quite far forward, such that the back of the pocket is often under the middle of the foot. This means that, with your full weight focused in a neutral position - back near the mid-foot - your weight isn't getting put through the pocket and the pocket stays very open (and fast). Great for a fast-gliding striding ski. However, in order to get the ski to kick you've really got to kick through the ball of the foot. If you tend to initiate your kick farther back on the foot the ski will never feel terribly secure. It's possible to find 812s with a more neutral pocket position. They're not terribly common. And when you find them they've got to be fit a little bit stiffer than Fischer's standard recommendation. This is because the standard recommendation is based on the expectation that a neutral position full-weight load will not significantly load the wax pocket. By getting a ski that will load the pocket in a more neutral position you've got a greater mechanical advantage over the pocket with your weight a bit back on the foot, but you've also got to be careful to keep the ski fast enough at full weight. I've got a friend (my first ski coach) who is a very accomplished skier but who has an upright technique and tends to load the ski through the back of his foot. I've picked him a couple of pairs of 812s, and while he can ski them by adjusting his technique, he isn't terribly comfortable on them. The second pair I got him had a pocket further back on the ski and is a bit stiffer than the first pair. SO - I'm guessing you may be experiencing an incompatibility between your position on the ski and the design of the ski. Your Atomics have a very different design with a more traditionally positioned pocket. Options: You should consider Fischer's new Wet snow ski. This ski is based on the 902 mold rather than the 812. The folks at Fischer claim that the pocket is still an 812 pocket. I'm not convinced. The reason I'm really excited about the 902 has much less to do with the tip and tail splay (which are the immediately visible characteristics) than with the action of the pocket. The wax pocket is positioned more traditionally under the foot. It's plenty long in most cases - around 30cm in front of the balance point and back to the heel (or even a little further back)under the foot. But the cool thing is how "active" the pocket it. Most ski tend to get progressively stiffer as they get closer to closing. This means that you reach a point of diminishing returns in grip pay-off for added "umph" in your kick. The 902 pocket tends to stay soft throughout the closing action. There is a lot of movement in the pocket for relatively little added load. The way I quantify this is by taking two flex measurements on classic skis. First I measure the load required to close the pocket to 0.2mm residual camber under the load - a pretty standard "closing flex" measurement. But then I measure the additional load required to close from 0.2 down to 0.1mm as an indication of how much weight willbe put to the wax when you kick. Typically an 812 will require another four or five kg to move from 0.2 to 0.1mm. The 902 tends to be much lower than that. Kris Freeman has one pair that is only 1 additional kg. The magic is this (using Kris's best pair as an illustration): you have a ski with a true half-weight camber height of 0.9mm (that's very high-plenty of room for klister or binder), but it closes at something like 57% body weight. And then, once you've got it "closed" it's putting a huge percentage of your weight straight through the wax. Additionally, it's not as position-sensitive as the 812. I thnk the 812 is an awesome ski for a huge number of people. It's a "flatter" feeling ski and tends to feel like automatic roller-ski kick for somebody who's natural kicking action is through the ball of the foot. But I think the 902 is a really exciting ski for people who want a more traditional feeling ski (forgiving of a more neutral position) and a very active pocket. For the right skier the 902 is close to a do-everything ski. I use mine 90% of the time I got skiing and love it. There are options from other companies as well, but since we started with Fischer I figured I'd focus there. Sorry for the (typically)long response. Let me know if you've got additional questions.

A couple years ago I ended up getting a pair of 812 plus and a pair of
812 cold with nearly identical flex numbers. I find that I like the plus in more conditions than the cold (because I have an easier time getting it to kick). The cold works well in, well cold snow. This may be a variance seen from pair-to-pair, but I tend to wonder if the difference is between the flex of plus and cold skis? BTW Nathan, MN conditions are old, man-made snow with an occasional dusting of new snow. The new snow tends to screw up our rollerski training and cycling. Jay Wenner |

stiffer skis this fall. I need a new pair of classics. Jay Tegeder "Keep training, lcyra never lies!" JT |
