In most cases if the kite is pulling you way too much after the pop
1. You're overpowered. Most guys coming from bridled kites are pretty used to being overpowered I find. This makes it easier to leave the water after popping obviously but you'll just be getting thrown and won't be in control. Trim your kite a little and go on a slightly smaller kite
2. Try riding hooked in and popping some small grabs and rolls hooked in without moving your kite at all. This will help you work out using the edge of your board effectively and improve your technique
3. Once that is sorted start unhooking and bearing off further downwind than you have been previously and then edging into some big raleys. Do this over and over and over and over until your body starts to remember it.
4. Try to keep your arms slightly bent so that you have a bit more leverage
