What size board are you riding? What speed and length are you riding?
While you are on the larger side you should not have to work hard to do a heelside w2w jump. If you have to "edge really hard and commit" the boat will win the tug-o-war every time when you try to spin and you will not get the handle back behind your back in the other hand.
With that said... you need solid wake jump. Once in the air you need a 2 handed pull to "put the handle in your back pocket" turning your head over lead shoulder at same time. When you feel the handle against you back hip release your lead hand keeping it as close to you body as possible and reach for the handle. Once the handle is passed to other hand the hard part is over and the rest will happen naturally.
The worst thing that can happen is you keep a lot of line tension or edge against the boat. The boat pulls the handle away from your body at about 210 degrees of rotation and you catch the dreaded back edge.
