Purchased the 4.3m. I'll start next year but I know I'll end up with two! Like like every wind sport I've done (sailboarding, kiting, kite foiling, winging etc) I get there is no "perfect" size. My gut is with a small ML for my weight more power won't hurt and it would be hard to hide/justify a bigger board at home! Appreciate the advise from everyone though - anyone selling a 3.6m PR cheap to complete my quiver?
