Thank you kiwiupover and FarNorthSurfer. I think more time one the water, speed, glide and riding the foil not the board in the jibe is the key. I experienced a wobble in my 85A+ mast with the CF300 I never felt with the HS232. That`s annoying. The idea was to +shim the CF300 with the result of more speed and stability. Is there someone who has tried this?
I started using a .5 shim (blue one) on the 300 tail after a couple of months learning to foil. Made it a little faster, but once i tried the 232 i sold the 300. I don't see the point of the 300 tail after you've started using the 232 tail. if you can foil ok on the 232 i don't think there is much benefit going back to the 300. The shimmed 300 is not as good for glide and speed as the 232.
But, I see in your first post that you're on a windsurf/WINDfoil board? If that's the case, it's probably a pretty big board to control. A WINGfoil board will be smaller and easier to control. When i was learning, even switching down from my learner 6'4" wingfoil board to a 5'8" wingfoil board made things easier for me gybing and riding switch. If you're on a windfoil board i can imagine the extra length is that much harder to conrtol through gybes etc.
