Hi Alex, After some feedback from other sailors I just recently decided to get a 2016 Isonic 107 and so far im absolutely loving it.
3rd sesh on it and Ive done 38.5 and its got more in it for sure.
my weight 92 at the moment.
I haven't used any of the boards you have mentioned but im sure there good as well.
