Hi guys..I have posted on here for over a few years and I love this site a lot. I am buying the two rotogrip balls up in my subject heading and I need some ideas on how to drill him. I like to throw from the 3rd arrow to the 2nd arrow and I throw the ball about 18mph. I think i am going to take the scotch brite to the apocly's so i can have a duller ball. any suggestions be appricated.
