Sounds like not fully decrabbing is part of your problem. Start decrabbing a bit earlier. The autopilot does it at 500. You don't have to start that early, but the stronger the x-wind the earlier I do it. That gives time for all of the other variables to adjust so you're not fallijng from grace at 10 feet. Add another 5 knots to your bug speed. This also helps to counter the loss of lift during decrabbing. With respect to derotation after touch down, you have to snatch it back smartly as soon as you see it starting to pitch down, but be carefull not to do it too early or you can have the opppsite efffect. It does have a tendency to pitch up with reverse selection. Lastly, don't stop flying your a/c just because you're on the ground. If you release your cross control imputs too soon your wing wants to come up and now your playing catch up at 170 knots.
