I think the torsion spring suspension being "falling rate" makes it so you need to adjust the springs for mountain conditions.I adjust my suspension setting for snow conditions pretty frequently. It takes about 30 seconds to go from minimum preload to max preload no matter how iced up everything is........ I guarantee its not near as easy with a coil spring.
The coil spring skid is "rising rate" so setting for rider weight and adjusting clickers works much better.
I just think there's been 18 years too many torsion spring apologists talking from a POV of purchase justification.
It's ok to accept that a mountain skid can work well as rising rate and still prefer a falling rate on the trail......
