I'm no expert, only been at it a month and a half or so. But I've hit a lot of jumps, and I always pop off the lip and tuck my knees up. Helps me clear the knuckle and maintain balance and control. Obviously with different grabs/tricks this isn't the way to go, but if you're just jumping, I'd work on getting the speed right and popping off of it.
If nothing else, it's probably something that's good to know how to do, even if you don't do it that much.
