i"ve been using the SA quads for the hollower stuff and mixing front SA w rear TS on the smaller stuff. i used the CM2 thruster the 1st day, but i think the quads r the way to go. either way, this board is fast. i've been fortunate to b able to surf it everyday from clean 4' to 2' mush. taking the day off today cus it is fricken cold. or maybe not.
