I am a high tracker and was recently advised by a pretty good regional player to try a pin down layout (long pin to Pap- under ring or bridge). What would be my advantage as I am a high track already so roll is not a problem. I would believe it to rev real early but with what expectation for? Thanks

If you track high, you will have to be careful to NOT put the pin too low. High trackers tend to have the "bow tie" moved and it will flare over your middle finger hole. If it does not flare over the middle finger it could hit the thumb hole also.

Pins below the ring tend to roll a little sooner and have a more even breakpoint than those with the pin below and between the fingers. Below and between the fingers is probably my favorite layout. SMOOTH breakpoint, but still good length and and still strong enough to handle carry down.

goodluck

Pin down meaning below fingers. Rags wouldn't this start up real early into roll or is all just early rev. The pattern we were talking about was 36-38ft and light-medium voulume with the shot being in that 3-4th arrow area with not much outward angle. With what you stated would that be considered a hook-set and wouldn't i ping corners due to not much entry angle.

It is definately not a hook set kind of reaction. It is just smoother off of the breakpoint than the pin high drillings. You will still get a strong entry angle.

According to Chip Zielke in his books "Revolutions I" and "Revolutions II", the relationship between pin placement and your grip centerline - the line drawn from the midpoint between your finger and thumb holes and your PAP (and NAP) is as follows:

The further "above" (towards above fingers) the centerline the pin is placed, the longer the ball will take to roll up. The closer the pin is to the center line - and indeed if the pin is placed below the centerline (towards the thumb) - the pin is placed, the sooner the ball will want to roll up. So up = later roll, down = earlier roll.

Chip also states what Excaliber does about being careful placing the pin too low - it can cause the ball to track over your finger holes, thumb hole, or both.

I'm also a high track player (my PAP is 6 inches over and a half inch up) and have two balls drilled with the pin about a half inch under my ring finger - which basically puts the pin 5.5 inches from my PAP and 2 inches above my grip centerline. The net effect for both balls (coverstock + drill) is good length with a smooth, controllable break point. I much prefer this over a ball with good length and a snap/sharp break point - especially when bowling on tough/tight conditions or on conditions where the pattern is breaking down rapidly. (I'd rather leave a 2-pin than a 4-6 any day)

Is there anything i can do to keep the track off of the thumb. I had heard a hole in the thumb positive quadrant will help raise the bow tie but what about the thumb hole. (more away pitch to try to increase both tilt and axis rotation?)
