You guys run 163 3s? Seems like more guys are happier with those than the 156. I spent nearly 2k for my setup, including clutching, got one of the first centerpunched x3s, and I really wish I could have made myself feel good about it, but even at $500 I dont think I could have! The only place I felt that it excelled was downhill braking, otherwise it was a trenching, planted, SOB, after going back to a stock track I do kind of feel like it took the fun factor out of the sled in ways. I do think coupling may have helped, but I wasnt gonna throw anymore money at the setup. Ran it in everything from sugar to heavy wet stuff to deep dry stuff and just couldnt get sold on it. The 2.4 just seemed to get up on the snow and go rather than dig a hole. Made the sled feel SLOW.
