I am a new Roto Grip user and have a question for you experienced Roto users.  I have purchased a 16 pound Epic Battle with a pro pin and 3 oz of top weight.  The pin to the RG(mass bias) is 7", and 9 1/2" to the star(cg).  Looking for some drilling ideas. I turn the ball pretty good and average about 17 mph, my pap is over 4 3/4" and 1/4" up.
Any suggestions?
