Im 5'8 and around 120lbs. In the last year I bought Line Blends (08 model??) size 165, found out they were too long for quick spins/park.. So i thought I would go a LOT smaller, so I tried the Line Invader JRs , size 145cm , after half a day in the park my legs hurt from hitting all of the jumps and the landings are not soft at all (i ski in NY and its not the best snow) . Decided to give the jrs to my brother, take my bindings from my skis (Marker M11.0 Frees) and mount them on another pair. I did some research and found the afterbangs, size 155cm (smallest they go) liked the look, construction, etc. But when I actually lifted them, they felt a little on the heavy side? Maybe Im coming from 145s but because of the layering or somethin, they fealt heavier. Im 80% park so i dont rlly care about powder/allmountain, etc. just park..spins, rails, etc. Would these skis be too heavy or long for spins/jumps?
