offset thumb

[stretchmike2005]

I recently got a ball from another lefty the jigsaw trap and the thumb is offset and i have heard this called a screwdriver grip i only had to enlarge the thumb hole to throw it and is seems easier to get more hook for me. does anyone else have a ball or balls drilled this way and do you like it and/or does it help your game?

Technically you're just lengthening the ring finger and changing the angle the fingers are drilled at. Some people find it to be more comfortable, so if it works for you, then great. Jeff Carter uses this technique. I personally wouldn't recommend this method of fitting because all you're doing is over-spanning your ring finger and in my experience this isn't good for your hand.
