The 5" pin and relatively high topweight limit your options. Depending on your ball's cg placement relative to a line from the pin to the mb, the best drilling for this ball would probably be pin over bridge. That would keep the CG near the center of grip and the balance hole size manageable.That is not an early rolling drilling, however.
Depending on your axis measurements, you may be able to place the pin slightly above and next to the ring finger and put the balance hole in a flare increasing position below the axis, on the VAL, but it will be a large hole. That may accomplish what you seek.
The best option overall may be to get a ball with lower top and a shorter pin distance.
Hope this helps.
