I have both 121" picked and 136" streched to 144" cobra this year. I love the ride of the long track way better over the bumps and it hooks better as well. Not to mention the deep snow advantage[thumb]
I just got a 136 this year and can really only find two cons to it. Those being the additional weight of the track and suspension, and it doesn't jump as well on the smaller stuff. That being said I love the 136 ride and performance in the deeper snow. Even the handling is still good.
