hull mod

my new ski still in the testing phase! I would like opinions on more modifications that would help in the performance.

Hi all I am about to start a build on a sn superjet and have not done glass work on a ski before. Would something like the west systems 105/ 205 or 105/ 207 be ok for working on this ski? I plan to do a nose rocker and shorten the rear. I am also looking for advice on glass/ matting/ suggestions...
