I was going to post a review from all the demos I have tried this week. I got on the following:
Never Summer SL
Never Summer Heritage
Lib Tech Jamie Lynn
Lib Tech Travis Rice blunted 157
K2 Turbo Dream
By far and away my favorite was the Jamie Lynn. Just so damn versatile. Took it in 2 ft deep powder, took it off piste on the natural jumps. Bombed it (100% agree with you, the board was stable. They actually all were, but the Jamie Lynn was by far the most playful). Pretty damp, and excellent in the trees.
I guess I have to say that the Jamie Lynn really was to me what I was expecting from an all mountain killer. I don't spend much time in the park, and like the other poster said, the TRS is supposed to be able to handle that better. But for the rest of the mountain, the Jamie Lynn was perfect.
***Sidebar - Never Summer. I'll get more in depth when I finally write about all the boards I tried in the review area, but I really am missing in the hype here. While I agree they are one of the most stable boards at high speeds, and they have great edge hold, does anyone just find their ride a little boring? They are planks. The dampening is awesome, but it almost numbs the mountain. I could see that being a good thing for the Raptor, or the Premier F1, but on the SL? The Jamie Lynn was so much more fun all over the mountain. I felt it was more responsive, and had more pop. Just my taste though, depends on what you are looking for in a board.
