I utilized the "Rico1" drilling on my Red Pin Classic Zone, but my cg was in line with the Pin and MB. If you lay out the ball with the drilling what do the static weights (with any holes obviously) come up to? This will give you a good indication about what the final weights could be. Also, exactly where does your thumb end up and what is the starting top weight?
To Dr. Rev's point the ball can be a bit erratic for heavy handed player's...even with a more controllable drilling like a "Rico1." I'm might hit mine with an abralon pad at some point in time...but as of right now I've got an awesome piece for practicing as it really tells me when I'm repeating shots correctly.
