For the uninformed (such as myself), explain why the reverse helix is inferior?
It's great for keeping RPM down at cruising speeds....thereby reducing noise and helping meet noise standards and upping MPG...something Doo must consider.
The heavier/bigger the track and the more load applied (like seen in a mtn situation) the shallower a helix needs to be to maintain belt squeeze/provide quick backshift. A helix should (IMO) be matched with the amount of belt contact area....so when you shift out farther, the helix needs to apply more squeeze to reduce slippage/heat. A reverse helix is doing the opposite....making more heat and slower backshift, especially after repeated runs at a hill.
Of course it's not JUST the helix, the entire primary/secondary setup has to work "together".
We'll be looking for gains for the climber/boondocker as soon as the snow flies.
For alot of guys, the stock setup may be fine....just depends on the type of riding you do.
