More good stuff mate. I have ordered the screws and will fill the holes in!
I was in the process of aiming that direction with the fins. The ones I got with the board (82l) for recommended quad mode are too small (13 &11) for my 5.5m. I have run the 15 twins with the 11s in front. This is too big but works ok.
I was planning on getting the K4 14s and 8s. I then have the option of trying the 15 twin with the small 8s in front or the 14s with the 11s in front.
Do you have any problems planing out of gybes? I used to have no problem but with this board I'm struggling to exit with speed. I find it incredible off the top, the bottom turn doesnt seem any looser.
