Get it, then you are right Blackrat, sorry, can only say "my bad", and not yours
A few of these max race foils are not adjustable it seems - this makes sense in a way if the "golden" angle is found, which it most likely is now after so many years of racing.
Luckily it does not seem to be fixed for freeride and wave foils, so here you can adjust to your own liking
Good, as so many of us use them differently and on a lot more different boards also.
Eventhough, I dont adjust on mine anymore, only to compensate earlier if I got a board where the straps where not correctly placed - but then the board does not fit the foil anyways...
Strapless it is only an issue if way off from the start - but this might be the case with some, definitely.
Could also be the foils default is not to your liking, and then you need to tweak it.
Rider weight could maybe play a role here too ? But I doubt it - I think it wont matter, will be taken out of the equations luckily.
