Basic flex seems the same nose to tail. I ment to check torsional flex today but forgot. I'll check tomorrw. Stability at speed felt great. I never felt it getting loose. Carving with the shallow cut is taking some getting used to. You can't rush the turn or your body will get ahead of the board. I can't compair the pop to anything besides my regular camber TRS. I'm going to be riding my friend 156 NS Revolver sometime but I don't know when. About the rocker/camber profile. It is the same idea as Neversummer but not as rockered. Sitting on my kitchen floor the board is nearly flat with just the weight of my bindings.
