Remi, I am not planing to buy a bigger sail than 10m2 so I find your answer very usefull.
Ken, I am sailing on salt water (CROATIA-PAG) with Gasstra GTX 8,5 and old F147 on 7-10 knots (not sure how many knots exactly), but it takes lot of pumping. On a bit stronger wind (10-11 knots) i sail vary fast.
Remy & Ken I´m asking your confirmation will the ISONIC 150 with OVERDRIVE 9,7 can give me the same experience as the old formula on 7-10 knots???
Greetings from Croatia!
