Lets see...this is my experience with Dynastar. It is slightly limited but here goes: I used to just ski all mountain, through my first two years or so of high school. Then at the end of the season two years ago, I reasearched heavily and bought a pair of Troublemakers. I have skied them for the last two years and they are absolutely awesome. I have tried on a friends pair of lines, salomons, and scratches and nothing compares to the feel of my dynastars. They have awesome pop, going forwards and hitting jumps switch. I have just begun hitting numerous boxes and rails this year and the edges are absolutely flawless. The only few bad things I have found is that they are not quite as soft as I would like, they are a little thin but not too much of a problem and they are hard to do butters/manuals or whatever you want to call them. Overall, these are by far the best skis I have ever ridden and my edges are in perfect condition. I have skied these at least 60-70 times and they are holding up awesome and I beat them up pretty badly. Now I can imagine that if you are stomping onto rails, or disastering them the edges might get damaged, they are built a little differently than other skis I have seen but for everying I have been doing, they hold up awesome. If you are looking for one of the best park skis, that can handle all-mountain awesome, and especially groomers; than deffinately deffinately get the TM's.
