I have read several bits of information both here and on Bowling Chat. Here is my question. In your opinion, if you are drilling up your arsenal if you use either the Dual Angle layout system or Storm's system, is it advantageous to drill all of your equipment basically off one standard layout and just change surfaces? I ask this because I drill off the Dual Angle layout system. Most of my equipment is drilled with 50x3to31/2x50-55. I see different movement off the breakpoints and altering the cover also enhances these different movements. Just wanted to ask. I did , once drill a ball with 30x3x48 and the thing did nothing. And was to be an aggressive piece of equipment. Also, the pin was below my ring about 1". Stats are tilt,11.5, rotation 50-55, speed off hand 17, revrate 320. Lefty. ( don't say anything!!!). LOL. Thanks for the time and help.

Ron, my apology. I miss represented my statement after sending. I had another ball driller and I must admit, he was fresh out of the beginner class. I had not received my equipment as of then so I had him drill this piece for me. I had given him the layout I wanted and he drilled it and later I picked it up. I have not measured the layout as of yet since it was just the other day. But I will see what angles he has drilled this  with.Thanks for your response. I know from the classes I have attended over the past 10 years, especially the dual angle classes with Mo and John, that usually there is a 70+ val angle that puts the pin in this position. Guess that is what I get for allowing someone else to perform the procedure . And me not being there . Thanks again.
