Wondering if a starboard 2019 isonic 91 is a suitable super light wind board as the dimensions are nearly the same as a jp slw. 7cm shorter and 1cm less in width, or are these for racing and harder to ride than the Fanatic falcon LW and jp slw?
Exactly. Isonic meant to be ridden with deep angles overpowered while the slw can be sailed underpowered to powered without issues.
That said I used a formula board (old school) for recreational purposes and all I had to do was use a shorter fin.
I went from a Starboard UltraSonic147 to a Patrik Slalom 150 then140 slalom. The 150 was awesome to ride while I've not used the 140 much. The US was great too. We have 4 US147s at our local and me on Patrik.
