well ordered a 15# 3 inch pin from bowling.com last sunday night. came in today, kind of disappointed it came with a 1 7/8 inch pin and 3 oz top weight..possibly thinking about returning and trying again for that 3 inch pin I ordered ,maybe try buddiesproshop.com.
what kind of drilling could I do? I was wanting something for heavy oil,but kind of nervous with this one. by the way, with all the writing on the ball I can't see where my track would be without rolling over something.
