When I fly a hull, I immediately uncleat the main as the hull rises but don't let any out until necessary. You won't have time to travel out and you want to be able to tighten the main sheet as necessary to keep the hull flying. I find myself pulling in and easing out the sheet as a balancing act to keep the hull where I want it. I always tell my crew not to make big moves leaning back as the hull rises since it will bring it right back down.
Make sure the angle of the block/jamb cleat is set right. It is adjustable and can make a big difference in how easy it is to cleat and uncleat.
After a while you will get to the point where you fly a hull while you are both on the wire. My son-in-law and I were out doing that with the wind between 25 and 35 mph. Our combined weight is about 370 lbs.
