Title: Two quick questions - short PIN length and TW for switch grip
Post by: lefty50 on September 25, 2016, 11:21:08 AM
MY APOLOGIES Doom... Title says Pin-PAP, I meant short pin length. Can't find these answers in my cheat sheet....

- What benefit is a shorter than 3 inch Pin to PAP distance? Which layout or characteristics favor a short pin length?

When using a Switch Grip, do I want a higher or lower top weight?

Thanks

Closer than leverage to your pap is going to reduce flare and get the ball to roll sooner and be smoother on symmetrical balls. I've had success with several balls that I put anywhere from 1 to 2.5 inch pin to pap on. Most recently, on a Grip It. I think I chose the wrong ball, because it's super early and smooth. I did have success with it on a Predator and Track Money.

Now, for a switch grip, any top should do, since you're going to be taking out more of the tw with the hole.

I was thinking that TW and BW are centered around Cg as the zero point, so Switch Grip takes out weight from the bottom side.. No?

No. If you have 3 oz of top, you're probably not going to end up with bottom. Depends on the size of the holes you're drilling, but unless you're drilling a ball with either 5 oz of top or 0 top, you will be within static limitations.

Apologies Doom. I meant short pin length, not PIN-PAP. What's the characteristics of a short pin length, which layouts favor it?

Oh, my bad. Shorter pin lengths (from CG) limit layout options, so you may not be able to tweak the cg to be able to add an extra hole. Also, they say pin ins have less flare potential. But if it's over 1.5, I think it's considered a pin out. I don't remember specifics.

I did type pin-pap before editing, so my fault. Appreciate the quick response, and thanks!
