Fascinating!
While I think the Crisis Pearl would make an excellent go-to ball for your situation, your being a high tracker makes a good but properly functional drilling and interesting question.
FWIW:
Thinking out loud - the milder (NOT mild!) cover and the higher RG makes me hesitant to place the pin above the ring finger, but its excellent control abilities for a resin pearl makes such a drilling very feasible. Yeah, My "wild" hunch is that pin above the ring finger, at least a 3" pin-CG distance ball, CG placed either directly below the pin or kicked out maybe 1" closer towards your axis point should give a decent workable reaction.
Remember that while the Crisis Pearl is weaker than the Thing Returns, it is not a weak ball!!
FYI the Crisis Pearl's cover is easily modifiable. Change it first if you're not happy with any drilling that you finally choose, before re-drilling.
