I'm guessing you are right handed also, so that is what my reply is based on.
So many ways to leave 10's. My bugaboos include muscling the shot, which will show a tremendous explosion on full pocket hits but the ten is almost always left. Hanging on to the ball too long so the release is well past the ankle on the slide leg gives lovely tens too. Then there is the ball that is too strong for the condition and burns up before it gets to the hole and also the ball that is too polished and is still revving in the pin deck area. Of course we can't forget the follow through to the center of the body instead of straight out, that's a great one to for leaving 10's.
Of all the things that leave 10's, the ones I'd worry about most are muscling the ball and and not following through straight out when you try to aim the shot at the pocket. Muscling the ball never gives it a chance to really work for you. Trouble is it is so easy to do and you won't always feel yourself doing it. Following through to the center of the body usually comes from not having enough hook for the speed and line you are trying to play, so you follow through towards the pocket to "help" the ball. Best way to beat it for me is to close the shoulders on the approach. By that I mean turning them to square at the pocket instead of square to the foul line. Then you can follow through away from the center of your body without sending the ball off line. No matter what the cause is, there is no magic cure. You have to figure out the cause, plan a fix and then practice, practice, practice. Good luck getting rid of those blasted 10's!
