For the lake at 85kg I'm still loving my KT Dragonfly V1 7' 19" 100L with AFS Enduro 1300/43 for tiny lake wave surfing. It is super tippy and definitely too small for me but learnt to SUP foil on it. It was my light wind wing board and now Parawing board so I've been really able to spend a ton of time building my balance skills on it and has payed off. When I do eventually get a new board think I'll go the same dimensions again.
My conditions for SUP foil:
