But I am with sboardcrazy, eventually, if it is not happening already, slalom above 20 knots in chop will become quite unfeasible!
If you want to get a unsticky combo that is particularly smooth in chop, get a Tabou Rocket 105 and pair it with a carbon fin of around 35cm.
Put a sail no bigger than 5.5m on it. I tried my 105 Rocket with a 6,3 but i noticed i could not maintain the lift over the chop and swell. I only now use my 105 with a 5m and 5.4m. With my 5m i use a 33 Tribal G10.
A smaller sail is lighter and needs smaller lighter components. A lighter rig will lift the board higher over the chop and it is much easier to maintain the lift for longer periods.
Rig should be around 9 to max 9.5kgs.
My 5.4m 3 cam race sail including all components - mast base, extension, boom and mast weighs 9.0kgs probably 2kgs lighter than many.
Put your mast base as far back as possible for increased lift.
Put your boom as high as you feel comfortable with. A higher boom increases lift.
All of the above should help make it more comfortable sailing in choppy water.
