Im looking at moving from inserts to no inserts.

Instead of plugging the fingers and re-drilling I was thinking about just getting finger slugs. I roll over my fingers when shooting spares so when we plug fingers on a ball it busts shortly after. Happens regardless of who I have had plug a ball.

Since my pro shop doesnt have them I was looking to order them.

What size would be the best?

31/32
1 1/8
1 1/4

thanks.

Get the size that fits the hole size that you have for your fingers. I am assuming this is 31/32. Install them with gel crazy glue, rout them down and redrill your finger holes . You will find you get a better feel without grips. I've been gripless for years. Natural holes give you a better feel for how much grip pressure that's being exerted on the fingers. You also don't have to worry about losing a grip either. You will find also that your release is cleaner and will get a better read on the lane condition. Best of luck.

And I had forgotten what size the finger holes were drilled out for inserts. I was thinking 31/32 but wasnt sure.

I also didnt know if I might need to go up a size.

+1 to cc i too started to get pain in my ring finger after only a few games i was glad i tried it on a old ball that i did not use much any more and like cc i went back to grips and the pain went away.
