handle pass

I've problems with the handle pass. I ride at a cable park and until now I managed to do some handle passes but it is really difficult. I am trying over and over again but can't get a better result. There must be a point I am missing.

For example the guy in this video can easily do the handle pass even by pulling the handle to his back just with one hand. My problem is I can't pull the handle to my back. The rope is always really tense and I don't have the power to pull the handle to my back. If I get away from the cable doing progressive edge (or If I pull the handle with both hands really strong) I create enough slack in the rope to do the handle pass but I only have time to do just one pass. I've seen guys doing surface 720 or over and it looks like they are doing the trick easily without wasting too much power to pull the handle, it looks like they can easily pull the handle to their back.

P.S.: If I use the classic method and keep the handle near to my hip with both hands, as soon as I let go one hand to do the pass, I can't keep the handle close to my hip anymore and the handle goes back to the initial position which is far away from my hip.
