This will wind up being very much a 10:30 drilling and will or can raise your track; so, you have to be careful exactly where you put the pin. Most often, one does not really put the pin exactly in/on the track, but you can, of course.
If you have a high track, definitely put the pin above the middle finger; it may still clip the holes. If you don't have a high track, you can put the pin next to the middle finger.
CG placement:
It winds up being a 10:30 type of drilling (for a righthander) because most people will keep the CG near the grip center. (So, this drilling will look a lot like a lefty's 10:30, the equivalent of a righty's 1:30 drilling.) Of course, you do not have to do this; you can move the CG into the negative side. If you do, you have to make sure the side (and other) weights are legal; so, you may need to put a weight hole on the Negative axis point. Since most balls drilled this way will not flare much, you don't have a lot of worries about the ball flaring over this hole. (This is looking a lot like a lefty's stacked leverage drilling.)
I tried this with a Visionary Green Gargoyle; I put the pin outside the middle finger and left the CG in grip center. It was an extremely limited use ball and did soften the backend, while slightly reducing length. I believe the reduced length was due to the 10:30 type drilling, which, when the CG is closer to the PAP than the pin, is an early revving modification of the pin.
I'd suggest this drilling with balls intended for dry lanes, like the GG, Scout, Tornado, Barrage, Sonic and the like.
