first of all, unless you track on your thumb, or on your fingers you can use different drillings. I roll on my thumb insert and use pin up, pin down, anything from 4 1/2 to 5 3/4 from pap. you have a lot of options. Go with that grand illusion. it's a much weaker ball than the cell pearl, just on core alone. drill it pin up, 5 to 5 1/2 pin to pap, adjust cover accordingly.
