I have had some issues with this board. Firstly though let me say I this board is unreal fun to ride. I wouldn't go and get another brand because of this. The tail has been splitting on the rail edge. I have just taken it in for the 4th time with the same problem and they seem to have finally worked out what's going on after seeing the same model coming in with the same problem. We ther it's just the 10' 6" I don't know but it seems to be with the bamboo top board.
Also seems to be the blue model. The guys fixing it are now filling the space between the outer shell and the core to make it solid around to the fin boxes. Hopefully this will be my last visit to them. I surf this board most of the time. Onshore slop, to real nice head high. Love every wave I get.
