I never really used them for any length of time.  I received a hand me down from my brother, so I changed out grips to avoid a redrill.  I used them on the next several balls.  I forget when or why, but I stopped using them.  I've never looked back.  Nothing to rip, change, or wear out.  I like the feel of a thumb slug to keep the feel the same from ball to ball, but I can't tell any difference with fingertips.  Plastic, urethane, resin, and particle all feel the same to me.  I definitely hit/hang up more with fingergrips.

For something even better, have KOTM drill oval holes right in the ball.  Most everyone has slightly oval digits.  It will give you a better fit and a little more contact area on your pads.  Once I got ovals drilled, I wondered how I ever used round fingerholes.

Hey Jeff since you are experimenting.....

try having an old ball drilled with sharp fingers. no bevel. just a touch of the sander to take the burr off.

it's a physics kind of a thing. leverage and all that. here is a simple real world mid shaker.

have some one hold a pencil horizontally.
place you fingers over it like your bowling.
have them pull away from you, not to fast or hard

you can not stop it unless you squeeze your fingers and grab it. and you know grabbing is bad. you are resisting harder more than they pulling

now have someone hold a thin rectangular object, that doesn’t flex like 1/8 aluminum.

now repeat the process and you will find out they have to pull very hard to get your fingers off and you have to resist very little.



talk about more revs and less grab. give it a try.

I thought it was weird also. but since doing it, I will never have my fingers drilled any other way.

it makes a big dillference when your form is right and you can feel the ball grabbing your fingers in the bottom of the swing instead of you grabbing the ball.

as a plus it's a good training aid. becuse if you squeeze, you will know it OUCH!

I have gone as far as having the thumb drilled sharp to stop grabbing it.

I remember we had an accomplished bowler around here we drilled a ball for once.

He gave us his specs and we drilled it. We took it off the drill press and handed it to him and said he could finish off the holes to his liking. He smiled and said “It is finished”. Walked out and started throwing it.

Would have made my finger and thumb bleed the holes were so sharp.

I don’t believe Norm Duke puts any bevel on his holes either.

I would assume most that don't use grips don't swell...at least enough to make a difference........

Better....much better!

actually with the sharp bevels the size of the finger is less imortant becuse the ball hangs onto your fingers. a little bigger is may even be better.

I have traded for a ball once that had the grips taken out. the holes were sharp and the span was close and I was able to throw it anyway.

You don't need a tight finger hole to keep the ball on your hand with this method.

I have tried every finger grip over the years. including vaccu-grips. they grab your fingers but I get more revs with my current drilling.

My finger are piyched away even. although I going to try the Claw grip in combination with a CLT .
