Thanks for this inside information from experienced people.
What I read is that it is very personal how/what you experience from the different boards. Thanks for that.
If I read this I also see that the futura is still closer to me then the Isonic. I like the freeride without paying to much attention how to take the chop. In this fase I go for the futura. In fact I just bought the futura 93 and 111

. With the F133 I have a nice quiver to go from 10kts to 30+kts.
Maybe you can add for me the best fin size for these boards. I will use 6.3 on the F93 and 7.0 on the F111. For the F133 I have a C3 Venom 44 and the one which came with the board.
