Sled Chassis v.2 is a 02, previously was a 03 (cased the first one). On the 02 I did the skid setback 3.5 back .75 down I think. With a 2" drop in the back. Track was a 15" x 151 camoplast challenger.
My guess was that you ended up with TOO much ski pressure, 3.5 back is pretty big on an 01', but the 02's already had the skid setback. (or was it a snowcheck?) Could have been the issue.....
I don't really CARE if I own the highest mark on the hill (but it can be nice), but I like the ZX for it's boondocking ability, I guess it really just comes down to personal preference, and personally, I am much more comfortable on my zx the way I have it setup than a rev.JMO
