what would the reaction be , having the pin drilled out with the middle finger

and kicking out the cg slightly pin approx 3-4"

this was suggested to me what is the purpose of drilling out the pin ??

my ball speed 16 - 17 mph
high rev rate 400 ++

My Animal is set up similar to that except my pin is drilled out in the ring finger. Is gives me a nice blend of length with angular movement to the pocket. I like the look I get with this drilling. I am more in the medium rev range versus your high rev rate. I hope this helps a little.

Having the pin drilled out of your middle finger will not change the ball reaction compared to not having the pin drilled out. The only reason that it would be placed there is that your ball driller is looking for a specific pin to PAP distance and it just so happens that it ends up being there. Without knowing your exact PAP measurements or ball that this is being put on, I can *guess* that this layout will give you above moderate length and a rolly/archy backend reaction without a lot of flare. Given your revrate and ball speed, this is a good layout for playing striaghter up the boards on shorter patterns where there is a lot of backend. Feel free if you would like any more information.

If the layout you want to use calls for the pin to end up being partially drilled out, or even just very close to the hole, there will be less potential for cracking if you slightly modify the layout to drill the pin completely out. -- JohnP

so lets say if the ball has an agressive coverstock, and I drill the pin out with the middle finger how much different will it be, then if the pin was above the bridge with the cg kicked out the same distance

This is not necessarily true. There are number of guys that use this, pin in the ring finger, cg out slightly, no extra hole. Enables players that come around the ball to get a hook/set or hook/stop type motion.

It doesn't hit very good for me, but have seen a few regional players use this with some success.

I agree with what Matt said about hooking back ends and such. This is a control drill, smooths out the back end motion, made the ball roll out for me, when I did it with a Track KO Punch a few years ago. Hit like a rotten tomato, never tried it again for myself, LOL!!!

The question though was does the act of drilling the pin out change the reaction. For most bowler the pin in the ring will be about 4 and 1/2" from the PAP, and kicking the cg pretty far out will put the mass about 3 inches from the PAP. This drilling will tend to make the ball want to hook/stop a little. The fact that the ring is drilled out doesn't change anything.

The further above the midline you place the pin the more the ball will want to push down the lane before making its move. So putting it above the ring will make it go a little longer than putting it in the ring.

I do this quiet often for myself often putting pins in my middle finger. My pap is around 4 1/4. I like pin to paps around 4 1/2 to 5 inches usually with cgs in the palm or maybe at most 1 inch away from the center of my palm. usually 4 1/2 to 5 inches with the cg around 4 inches from pap. I usually will get smooth continous reaction.

I often have the better part of my gear with pins on my midline or on the negative side of the ball for more stable reactions.

I agree with this assessment as well.

I have an interesting perspective on this because of where my PAP is. The "up" coordinate of my PAP is 1 1/8. Because of that, if you put a quarter scale on a ball, and lined it up so that you could make a line that went right through the center of both finger holes, my PAP is practically right on that line. As a result, putting the pin on a ball either directly above or directly below the ring finger hole is the same distance from my PAP--just about 4 inches. Putting the pin IN the ring finger hole places it only slightly closer to my PAP, so for all intents and purposes, all three of those drillings are the same distance from my PAP.

I notice a distinct tendency toward earlier reaction on the lane from a drilling with the pin below my ring finger. This is a favorite pin position of mine. Putting the pin above my ring finger tends to make a ball push a bit too much for me, even though it's the same distance from PAP as when it's below my ring finger. Occasionally, I'm afraid that placing a pin below my ring finger will make a ball want to react too soon, yet I'm afraid to put the pin above my ring finger because that position almost never works for me. On those occasions, I opt for putting the pin in the ring finger and get the desired result--a little more length than pin below, but a reaction I can control better than pin above. My Enriched Uranium has the pin in the ring finger. I notice no particular strangeness coming from having the pin in the ring finger hole. I imagine if you had a ball with a heavy flip block on top and you drilled the finger hole extra deep to take out a significant amount of core mass, you'd notice a difference, because you'd be lowering the RG of the core. I've never seen any particular reason to try something like that, so I'm guessing.

That's my story, anyway.

The other thing you have to worry about pin-down balls is whether it brings the track too close to your finger holes.

Before I started experimenting throwing with different axis tilts, I played as a high-track player almost exclusively. Now I can play anywhere from low-mid to very high.

When I'm high-tracking it, there are a couple of balls in my arsenal I can't throw (a L/L Yeah Baby and a Roto Grip Winning Streak) because of pin position. The Winning Streak in particular has a low pin to make it stand up and go into a roll earlier. If I'm not careful about how I throw that one, I'll track right across the the middle finger.

By comparison, pin over the ring allows me to do more things. My Cure has a pin about an inch over and an inch to the right of the ring, and I can almost lay that ball on its side. The ball also has more of a hockey-stick look to it.

Just by coincidence, I have an AMF Velocity that has the pin drilled out of the ring. We did that because we were trying to get the ball to go long/hook late, and were trying to do it on a short-pinned ball. Pin-to-pap distance dictated the location of the finger holes, which just happened to go through the pin. The problem I found with that particular ball is that I'm almost exclusively limited to a low-track release axis, because when I release any other way, the weight block pushes the ball through the breakpoint. It's drastically different in the reactions I get, therefore I've got to be careful about how I turn it loose. Lots of over-under if I'm not careful. Even putting a weight hole in the thumb quadrant didn't help much, although it did help the ball stand up a little sooner. But when I do hit it right, the ball is a tank on wheels.

In summary, simply saying "I want to drill out my pin" does nothing for you; it's all about where the pin is in relation to the other measurements and what you're wanting the ball to do.
