Pin lengths on Pro-pin balls?
« on: April 26, 2007, 03:07:59 AM »
I was wondering what kind of pin distances people have seen on Pro-pin balls. I know the spces say the pins will be greater then 5" but I was wondering how far out the pins have been on some of balls.

5-6" is common, but can be as high as 9-11".  You basically have to have the core below the midline of the ball to create a 7"+ pin out, whereas for less than 6", you just need the core off center (not by much, we're talking 32nds and 16ths of an inch).

If you ended up with a 9" or longer pin, just put the pin at the north pole, mark the south pole (13.5" from the pin), and call that mark the anti-pin.  Use the anti-pin like you would normally use the real pin, and that ball with a 10" pin now has a 3.5" anti-pin.  There are plenty of balls out there where the core has been flipped over (DT Elements up to the AU79 and after the ZR40), inverting the core is not unheard of.

I'm familiar with the inverted core technique, but what if it is a ball with a MB.

Are these blems...I thought I read some other thread that stated so.  What is the typical reaction?



These are 1st quality balls.AS far a a reaction it depends how you have it laid out. One thing for sure pro pin balls aren't for your average driller.

Calling it "pro-pin" sounds so much nicer than saying "blem", doesn't it?

From a physics standpoint, I believe the MB will stay the same when you flip the core upside down.

I've got one with a 11.5-inch pin. At least the MB and CG were in a straight line. Drilled, the ball's pin is about 1:30 to the ring finger and up a couple of inches, MB is in the strong position and the CG is back around the ball way under the thumb. We had to drill a moon crater out of it to get the statics legal.

Talk about a unique reaction -- totally hook/set, and the ball does all the hooking it's going to do in the heads and mids.

I've got another Paradigm with normal specs and the two balls aren't even close to being the same.

They're great for filling specialized gaps in your arsenal, but don't try to use one as your benchmark.
