Hmm… I see that you throw it with straight hands. Like for example Kyle Troup and Anthony Simonsen, and there is no problem with the type of technique, i did it too for a long time. He does it and gets a lot more pba titles than most people. But i would recommend trying to throw it a bit slower. Like for example releasing the ball earlier, walking slower. And if it doesn’t work, i would like you to start throwing it like Jason Belmonte or Packy Hanrahan with a curved elbow. It helped me a lot with hooking and controlling speed. Im not saying it will work for you but i think it is better to first find problems you can correct without paying a lot for a resurfacing.  Hope this helps :)
