Main sail size for Sunfast 35?

[andrewsarratt]

My sail maker has mentioned my Main sail size that came with the boat is to small@ 29.6 sqmt. He advises me that i could get 32 sqmtrs and really help upwind performance where we struggle. Also he says the Spinny could be 92sqmtrs instead of 78 sqmtrs. For the extra couple of points on IRC it could make the boat much more competitive.
Any comments from other Sunfast 35's Andrew

Find Tim on here,

He races an SF35 what appears tobe pretty extensivly, as does one other fellow. That looks to be a similar increase % that my sail maker has mentioned to me that I can increase my MS on my Arcadia with a larger roach and full battens, ie 165# to 191#, not sure of the sq M equal vs teh sq foot measure.
