Hawaii_boi I got my 5'2 SP in TT 5fin FCS2 From Surf Garage. I like it wayyyy better than my old 5'3 TT BP. Been riding it for the past 2 weeks, that we had or had lack of waves. Catches everything. I weigh 170. Now stuck between a 5'8 Uni or 5'9. I want a board between my 5'5 VG and SP. But I can see me riding the SP 95% of the time either way.
Actually have only ridden the SP as a quad. The fifth nubster fin would probably give you a little more hold, but since you're working with such a wide tail, the difference between four or five fins I imagine would be small.
