for your high wind board, get a wave board. the only thing a FSW brings to the table is early planing and a bit more speed sometimes (boards such as the starboard kode and the fanatic newwave are crazy fast too), and for your high wind board thats not a huge issue, you want control and manouverability.
I don't understand the obsession with the FSW boards, I have one, its a nice board for light winds and early planing, but I don't rate it in waves at all, thou i'm only a beginner wavesailor. Maybe a different fin would change things a bit, but its hard to work past the lack of rocker. my smaller waveboard, a fanatic newwave will carve circles around it, and carry more speed through the turns.
these two links are probably pretty handy:
