Can someone help me decide what drilling to use,number two or number three on this ball? I know number two states med oil while number three states heavy oil.I bowl on what i would call med oil but i am a little rev. challeged and i need a little help knocking down the ten pin so i thought number three might accomplish this but then i thought it might also burn up early and leave a flat ten pin.Now if i go with the number two drilling will it be strong enough to carry thr ten pin? If this helps i throw about 15 mph.and my pap is 4 3/4 over and 3/4 up.
