Tried many various foils and only one gave me real fun in waves.
Moses Silente - very low AR, delta shape front and back wing, short fuselage - the fundamentals of wave riding with foils in my mind
I do not want to touch any high AR foil going to waves. Medium? Somehow feel not right about it either.
Low AR turns faster, requires less speed to go and is slower than any medium or high AR.
Slow speed in waves is a crucial factor in my mind.
The slower foil than it should be better foil for waves - especially riding down the face as you can stay on the same wave instead overtaking it being full powered.
Short strut? Never tried shorter than 90cm so cannot say anything.
BTW. What is a point to have 3 straps riding waves?
The front foot positioned at the center line gives better control riding normal or switched position.
Obviously strapless is the best way to go but if someone needs straps I would recommend just two.
Last thing from my personal set up - I feel more comfortable and somehow right on a classic wave board than a short boards foiling waves.
