I have a buddy that rides the ar7's and i ride THalls... the T-Halls are softer than the AR7's and have a little bit different flex pattern. anyone feel free to correct me on that one.
Mine are easy to butter on, but i am 6'1" and have the 176's so i have softened them up alot. I really like them for rails and they perform awesome on jumps as well. Super tough base.
I haven't tried the alpha 1's but know a guy at my local hill who rides them and likes them alot. He says they are a little stiffer but super poppy.
hope that helps
