First, no I'm not skiing at an elite level, so performance doesn't matter "as" much.
Skied all my life, am now 34 and started course work two seasons ago. Still breaking a few bad habits but am doing work at -15/32. Expect to be at 34 shortly (knock on wood, been making big strides here lately).
I ski with my coach 3-4x/week. He injured his ankle in a set of hybrid bindings after changing from Powershells. I ran is middle school, highschool and college, so my ankles and knees are toast. As such, I'm aware that I run my boots too tight now b/c I'm trying to get them stiffer.
I looked at going to FM's last year but decided to wait till my skill set improved. I know that I don't need them at this level, but I want something stiffer (and safer) than the bindings I'm in now.
