I skied race skis in the park for 1 1/2 years before picking up twins. I just had to skip 540s after learning 360s, and go right to 7's. Once i did get on twins, i noticed much more pop, and just a better more natural flex. So, if your in park skiing for the longhaul, or even if you ski park some of the time, sell your current skis and buy some twins. You'll still be able to shred all mountain.
