I don't know about how you should drill, but I will tell you that you'll probably need to adjust the surface some to get rid of the over/under created by too shiny of a finish. Mine was too clean OOB and tended to slide right by the breakpoint if I missed left a pinch, and as soon as I got it to the friction, it looked like somebody kicked it left. Lightly knock some of the polish off with an abralon pad, or completely remove the polish and redo it to a lower shine. For me this really brought the ball to life, it's now the strongest ball in my bag as far as total overall hook goes, and it's much more controllable. (Granted I haven't gotten a fair test of it yet -- they changed the oil pattern on my Tuesday league two weeks ago to a very, very wet/dry wall that I cannot for the life of me figure out. Everything in my bag gives me an over/under look on this currently...)
