I wanted to give this board a few days of riding before reviewing. I've been riding for 10+ years and also believe that a good rider can ride well on any board.
That said, the F1-R has been a joy to ride. I haven't noticed any loss of edge hold and only a slight loss of turn pop due to the rocker-camber configuration. The increased level of forgiveness the board provides on flat spins and spin landings make the benefits far outweigh the unnoticeable cost.
Note that this is probably not the best buttering/park board. It's very stiff and it's definitely not the lightest board around.
Another thing to note is it does seem to dampen bumps pretty well. I've found myself charging through bumps I would have previously avoided.
