G20, G32, Polar Extreme

Folks,
I have packs of three colors of old Swix "Cera System nordic racing
glider" wax. The temp range is the data printed on the packages.

Polar Exteme (+7F and colder)
G20 green (+18F to +7F)
G32 violet (+28F to +10F)

These were made when Swix had separate glide waxes for nordic and
alpine. Around 1994 or so, Swix changed the product line. Glide wax was
now a common wax for both nordic and alpine. At the same time, they
changed numbers and temp ranges of the waxes.

Since these three old Swix waxes were widely sold, a lot of skiers
have experiance with them.
What was the real world ranges of these waxes? Did they work well
throughout the published ranges, or were they best in part of the
printed range? Were any of them known to still glide well warmer or
colder than the printed range?

I know the current Swix CH4 and CH6 (the waxes that replaced Polar
and G32) are known to have wide ranges.

CH4
Old Swix wax book says this is an improved Polar Extreme.
Temp is +14F and colder vs (polar ex) +7F and colder.

Before CH7 existed:
CH6 (violet) +25F to +14F
CH8 (pink) +34F to +21F

After CH7 existed, CH6 became "colder" and CH8 became "warmer":
CH6 (violet) +21F to +10F
CH8 (pink) +34F to +25F

I have the new CH glide waxes too.

By the way, two years ago Swix changed the colors of their glide
waxes (the waxes are the same).

Old colors:
CH4 (ice blue)
CH6 (violet)
CH7 (white)

new colors:
CH4 (green)
CH6 (blue)
CH7 (violet)

So Swix made four violet glide waxes:
violet +28F to +10F (the old G32)
violet +25F to +14F (CH6, before CH7)
violet +21F to +10F (CH6, after CH7)
violet +28F to +18F (CH7, new color)

My guess so far is:
Polar Extreme: I should consider this a slightly colder CH4. Use this
up in the package range of +7f and colder. Not as fast as Start Green or
CH4, but OK.

G20 Green: Swix did not seem to make a direct replacement for this.
CH4 and CH6 only overlap for 4 degrees (+14F to +10F) so this could be
better than either in the low teens?

G32 violet: this wax was very popular with downhill racers at the
time. My guess is that this is very simular to CH6.


This is all for ski touring, not racing.
