Wakeboarding and snowboarding grabs..difference???

I was snowboarding yesterday up at Bluewood and they don't have much of a terain park or a lot of jumps yet, so I built a small kicker and was going to practice my grabs. I can jump off it fine, but when I try to grab the board, I get all off balance and can't grab it. On the way home I realized I do the same thing wakeboarding. Is it because I'm trying to go to the board instead of pulling my legs up higher to bring the board to me? Any suggestions or drills on how to work on that or which grabs are the easiest to learn??

Thanks!
