iS145 vs. FT148

[paulk]

Hello Roger,
from other threat I understand you have these two boards. I know you had 'plenty' of FT148. Did you have a chance to test the new iS145?
Could you please comment on differences in these 2 boards w.r.t. (this is a priority order for me at least):
1) Early planning,
2) Upwind /Downwind ability
3) Higher wind handling (say ~15knots)
4) Is it possible to put on iS145 a bigger fin, say 65cm (I know FT148 is fine with 70cm)

Thank you in advance for your help,
Paul
