I ride a 159" x 2", coming off a 136" 1.75". Granted they're different chassis (wedge to edge), but I can handle the 159" well enough to have alot of fun. The bigger sled has twice the power (at least) and weighs maybe 50 pounds more, on top of that I've gotten into alot better shape since last season. Geared deep and loving it. I'm on the tall side, 6'4" but not on the heavy side 165-170. I haven't ridden the new sled in seriously deep snow yet, but am certainly looking forward to it. Comparing edge 144" to the 159", I enjoy the big one alot more...
