Hey,
I'm 5'8 140 lbs. I have been surfing consistantly for about 9 years - I would consideri myself intermdiate -advanced. I normally ride a 5'10 shortboard, and a 5'5 19 1/4 fish. I recently purcashed the 5'5 Firewire Activator. The board turns perfectly and slides great, but the problem is in waves that are 2-3 feet, the back of the board sinks. Also, the board doesn't seem to have a lot of drive because after I do a trick, the board seems to sink even on a steep wave.See below url for the board. I currently ride it as a quad, and the fins are quite small. If I switch it to a 3 fin setup, and put in extremely large fins, would that increase the drive? Any advice? I really don't want a bigger board or thicker.
