To add to what Dyno-Joe stated, keep away from any drilling that the pin is 5" or greater from PAP (usually anything with pin above fingers). I've also noticed that pin-in balls aren't good for people with high tracks.
From my experience, any leverage, axis-leverage, or any variations of those does a decent job of pushing the track down enough to miss the fingers and thumb.
