Matt:

I've seen discussions on the tracking issue with the SkiGo somewhere on the intertubes, so you may want to look around. (And I'm assuming BNS could fix them for you.) If you have a strong preference for ratchet up front, are you able to just switch the wheels? Anything else you're unhappy about with the SkiGo's???

I've been quite pleased with Swenor's (with #3 wheel)--got just what I was looking for in terms of very smooth ski (really feels like on snow--easy on the joints) and enough resistance to be able to comfortably do diagonal stride on flattish terrain.

I had the ratcheted wheel up front on my V2 9000's (which are actually longer than the SkiGo's) and thought that was critical, but don't notice any real difference in terms of training effect with ratchet on back with Swenor's (may be due to the flex of the shaft).
