Hi I just get a new custom made JDP SUP 7'6 X 27 x 86L with heaps of tail rocker replacing my 7'10 ECS wapon 87L with little rocker which I snapped. I have found the new SUP good in more powerful waves as the high tail rocker allows the board to get more vertical and easier to make floaters and tight snaps. However on small weak waves which I mainly ride it in (I ride a surfboard in powerful conditions), I can't get enough speed, or seem to lose speed quickly in the dead sections since its so light only around 5.5kg with lots of rocker. Was thinking I should change fins to more of a twin fin setup (large sides small trailer) for more speed and drive. Its only has thruster plugs. Any fin recommendations for more speed in weak small waves?
