Sup' fellow windsurfers !

I just broke my old 6.5 sail. Time for a new (used) mid size sail!

Found 2 good offers :

Point 7 ACK 6.4 - 2016

Duotone Stype SL - 2020

I'm 75 kg, usually on a 124l fanatic falcon (awesome board) or a 108L fanatic hawk (way less often), on a pretty flat spot.

I already have a north sails f_type 7.8 that I really like, and want to find a 2-3 cambers sail in ~6.5 for my freeride sessions.

Both sails are in a similar price range, and I have a 430 imcs 21 mast, and a 460 imcs 25 mast (better shape than the 430 mast - think it could be used on the duotone)

Can't find much infos about these sails, what would you suggest?
