IMO, the newer shapes are nothing like your full cambered Nidecker. Super easy/forgiving to ride. I typically ride a 'race' board, 'all mountain', on all but powder days when I reach for the softy setup.
I picked up a Donek rev 157 demo this fall and finally got it out this last weekend. I think it may just be my new favorite board. Sean's new boards are every bit as good as the Kesslers at a much cheaper price. I agree though, it's difficult to pull the trigger without being able to demo.
I weigh ~150lbs, fwiw.
