780 is my go to foil from 15 to 22 knots then I switch to 580. The 780 has a lot of lift and doesn't require a lot of energy to get up. Chop is your friend, use a small wave, point down wind and you should get up easy. Sounds like you could be coming up too quickly, either use a smaller wing or try moving the foil back 1cm. I also think that the 180 tail has too much lift, I prefer the 120 but you could try shim it. For reference I am 88Kg 60L board
