I agree with Callen on this, with what he says on you approach/cut into the wake as your definitely flatting out before you hit the wake.
Aside from that I would work on focusing on your handle pass. Looking at the video you are passing the handle with your front/lead hand way outside of your body. You're still catching the handle but its hard to keep the spin under control with your arm out that far. Taking that a step further when your ready to take that 3 to 5 or 7 you need to have that handle in tight. If you look at the video that J-Rod posted you can see when he passes the handle the rope is tight in the small of his back. Having the rope in tight to the small of your back helps you keep the spin and landing under control as you can adjust as necessary when you land with your arm to not slip out and actually stop the rotation of the spin.
It's all about muscle memory here. A good training tool I use is a handle, a bungee, and a weighted milk jug. Take a spare handle and attached about a 2 feet of bungee tied in a loop to the end. Then fill a milk jug about half full of of sand. Use this as a tool to help learn the muscle memory of passing the handle in the small of your back in tight. The idea is simple you start passing the handle around your body keeping the rope in tight with each handle pass, as you increase the speed of the handle pass the bungee will stretch and create more tension, hence working your arms more. You can even start spinning your body opposite the handle to further increase the speed of the rotation.
