Ball layout help

[andrae1982]

Hi guys. I was wondering if you could give me some information. I've just recently got into bowling pretty regularly. I have a supernova and a x factor bowling ball that I both bought used pretty cheap. Cant afford brand new. I figure I can build a bigger arsenal buying used for now. Well I don't know to much about drillings. I'm right handed. My supernova was plugged when I bought it so I took it to my local driller. He asked if I wanted to ball drilled aggressive and I told him yes. He ended up drilling the ball pretty near where the plugs were. He also drilled the weight hole again. The pin is right above my ring finger. Works great. My X Factor fit pretty good when I bought it and the pin is a couple inches right of my ring finger. I like its reaction too. Well I bought my third ball the other day. An old Columbia piranha/c in great shape for $40. I got my driller to plug and redrill this one for me. Well he didn't ask me any questions this time and just drilled it up pretty near the plugs. Also he didn't plug the weight hole he just left it where it was. As I said I don't know much about drilling but it just looks odd to me. I haven't seen any other balls drilled like this. I don't want to question the guys work so I was hoping someone could tell me if this drilling is okay. Could you tell me what kind of drilling this is or what it is meant to do? It also looks like to me that it will roll over the weight hole. Is that bad if it does? All information is welcome. Thanks in advance.

andrae,

this was most likely a pin on PAP drilling for the original owner of the ball.  without knowing where your ball track is at release, it is difficult to tell if this drilling will work well for you or as you intend it.  holes near the bottom of the ball were common in the early 1990s when this drilling was more often in use.  if your track is similar to the original owners, you will most likely not hit it.

placing the pin near the players positive axis point will reduce track migration severly, making the ball track much thinner in appearance.  this will help the ball go straighter through the front part of the lane and hook smoother when it encounters friction.

good luck and good bowling.
