Last season i was using 161 line invaders, we have a ski/snowboard freestyle camp at the end of each season. At the camp we were allowed to demo 4frnt skis, i demoed the 08/09 175 4frnt TNKS and i adapted to them in 1 run. I instantly enjoyed the more stability i had with the 175s, i actually enjoyed those skis 2x more than my invaders and i had only ridden them once. However I dont really liek stiff skis but it wasnt hard at all to adapt, so you def shouldnt have any problems.
