Hi,
used to windsurf 10 years ago and now getting back into it via windfoil. Nowhere near me to try kit, so after tons of research, youtube etc decided on,

slingshot levitator 150 (6"6 / 33 inch)
windfoil V3, with infinity 99 wing
rig used in this example -> 5.7 sail
My weight : 97kg/215Lb
My height: 5"11

Ignore waterstarts for this example. I want to be able to uphaul foil board.

With windsurfing i would put 1 foot either side of mast whilst facing mast and that would give good balance. with foil board the mast is so much further forward. where do you stand? I expected this kit to be stable and floaty, but submerged easily under my weight and the weight of the foil seemed to cause back of board to sink quickly. This is not stable at all and I'm struggling to find balance point. its worse when i do find balance, but once uphaul starts it can quickly tip to back of board and sink. Feel like I should have gone with levitator 160. I'll persevere and sure it'll click, but any tips welcome please. Thanks
