Pepin, not sure if you have followed the A Class vote a couple months ago, but there were some serious restrictions about length and other constraints. Im not saying that foiling is cheating, but its gone a bit beyond the premise of the curved boards intent(at least for the A Class)
If you want to foil, put some of those babies on your 5.2 and start your own class, but dont bring them into the A Class, we want something more "traditional".
