Soda - Skating warped boards is such a bummer. It doesn't really affect performance as much as it's just plain annoying. I've had boards from every woodshop warp (including South Central, Pennswood, BBS/Generator, PS), but Crail boards definitely seem to have a higher tendency than the others to warp if they are stored for a long period of time. Hell, there are new Crail boards on my local's board rack that are warped. I like Crail boards, but the warp factor always makes me think twice before buying.
