What a terrible set. The ball was hooking just fine, but I was throwing Brooklyn ALL NIGHT. I got one (1) shot in the pocket and it blew the pins up perfectly. That shot was millimeters away from the gutter.

If I'm not mistaken from my readings, when you throw Brooklyn, you're not throwing the ball hard enough. Which leads me back to not being able to have my thumb all the way in. Thus, I can't get any more swing without the ball slipping.

I think my scores were 83, 106, and 87.

Agh, the agony of watching that.

You're overthinking and trying to do everything at once. Break it down, back to the basics. You don't get good overnight, or with a new ball.

How do you put your fingers/thumb into the ball? Do you put your thumb, or fingers in first. You should put your fingers in first up to the first knuckle, then your thumb.

I've been having fit problems too. However mine seems to be quite different from yours. I have a free arm swing and before I even push away the ball to begin the swing I can tell that my thumb is not coming out. I am 99% sure that the ball still would not come off if I tried to do what you do to get the ball off. My thumb swelling has a lot to do with this.

Don't give up. Keep working with your Pro Shop until you get it figured out.
