You've got to realize that what you do or want to do with a drilling depends on the ball's design, core + cover. It doesn't depend solely on the drilling. If you drill 3 different balls (I emphasize, "different"!) with the same drilling, when thrown by the same bowler, they will or should get 3 different reactions and ball paths.
You're talking as if every ball drilled will get the same reaction when you put the pin in the ring finger hole. Maybe you don't intend that, but that's the way I read it.
Yes, Pinel has designed some of his cores, such that you'll get a very different reaction if you use a pin-up drilling (it is bad to refer to a drilling this way because the part of the reaction determined by the drilling ALWAYS depends on the Pin-PAP distance, the VAL angle and the Drill angle), than if you use a pin down drilling. In those cases (these "special" cores) pin in the ring finger will still be, in the vaguest general terms, half way between what you'd get with a pin-up drilling vs. a pin-down drilling.
