I can vouch for Mjunkie as he is my brother.
We ride with all different sleds and lengths, and even in deep pow he usually puts the hurt on us in a climb.
As he said, my pas sled is a kk 1150 162 challenger extreme, my sled is a bone stock 08 m1000 153.
I think that had my pa stuck with the A-20 in PP, he could POSSIBLY put the hurt on Mjunkies 141 in deep dry pow, as it stands, that little 141 is VERY inpressive!
For my pa, the extreme was a great track for all conditions.
I think that in this case, the comparison should be kept to deep dry pow only... In the more set-up snow, we can jump him off the line becase he spins, then he has to play catch up.
My stalker usually gets a good jump, but if my pa can hang on, he will jump us a few lengths right off the bat.
In set-up snow you can usually climb as far as you dare, so track length is not as relevant.
I also realize that conditions play a big role.
We used to ride with a modded reparis 800 144 that was VERY lightweight... That sled was unbelievable in deep pow... He switched to a 156 and it hurt him, so he went back to a 144.
IMO, light weight counts for A LOT... I have seen this first hand with my 1000... In the deep I think a 162 would help me a lot, but I still have a lot of weight to push.
I do however agree that with a long track you can manuver at lower speeds, and also start out much easier without trenching.
My pa can stop almost wherever he wants and get moving just fine... My brother and I tend to park in a track or down hill so we can get started easily without digging to china.
