What are some of the best ways to learn/practice handle passing on the water without just going for a W2W 3 and trying to figure it out? Just curious on some tips to learn/improve on handle passing while out on the water. Thanks.

Try some surface 360's. You may need to take your fins off to make the board slide around easier.

surface 360's at a little slower speed. then bump your speed back up and try a 1 wake 360. then try 2 wakes. if you are having trouble with the 1 wake 360, try them off the roll on turn around.

I know you are looking for on-water drills, but trampolines work very well for practicing handle passes

When im on the trampoline i can do handle passes perfect but when i get on the water my mind goes blank and still cant get em. I know what im doing wrong though, im not being the handle down to my hip. But when im on the water versus the trampoline, the tramp doesnt have much resistance so its easy to get it around cause there isnt anything pulling it away from you. Any suggestions on how i can remember to bring the handle down to my hip when im on the water??
