my mountain viper trenches very bad when I go to the mountains it is a 144 x 2 right now, do you think a 2.25 would be any better or skid swap is the better answer?
Skid swap. I hated the pro action skid in deep snow

Skid set-up is a major influence on trenching. A longer track is more beneficial than a deeper lug, it's about flotation. I am also not a fan of the pro-action, the only good thing about it is it is coupled. You need a balance of weight transfer and coupling. The transfer will get the sled to hook, the coupling will "help" stop it from trenching. As a starting point, set front limiter to max length. Front skid shock (spring) to softest. FRA in middle position. Rear shock (spring) softest. Test the sled on flat ground in DEEP snow. You should be able to feel the sled want to climb up on top of the snow, not push through it. This skid setup will 1) allow transfer with the long limiter and softer rear shock. 2) will couple sooner with the soft shock setting. For adjustment from here, shorten front limiter, tighten rear shock spring. The skid needs to work on the flats before it will work in the mountains. It's been 15 years since I played with the pro-action but this will give you a starting point....................SRXtreme

thanks for the advise, I tried a few different set ups last year, it is a great ditch banger but have been to the mountains 3 or 4 times and have played with the skid even while on the hill and just cant make it work for me. I may not be heavy enough to get the weight to transfer at 175lbs. shoot straight up a mountain and trench all the way ha even f7s can do better, and as soon as I carve the bottom washes out and I am in a hole. cant touch me on the trails tho.
