Start trying two handed grabs if you aren't going to hold onto the handle anyway.
Anyway it would be fair to say that I feel you and have been there myself.
Do progressive jumps. Start by not edging at all just let the boat pull you in and do a one wake jump. Keep adding a foot or so to that until you are wake to wake. Also, ride up the wake TOWARDS (not yelling just emphasizing) the boat not perpendicular like a slalom cut. Being a skier of old that is a mistake that puts me in a rut at least one or two sessions a summer.
