I personally have an Atomic Charge. Have it drilled pin under ring finger, and cg at about 4:30...small weight hole. Pin is about 2-3". I tried it with the box finish, and wasn't to impressed. Ball actually had a little over under. I hit it with a very light coat of magic shine, and that really brought the ball out. Very strong rolling, and currently the biggest hooking ball I throw. Much more consistent now with the polish on it, and it is always the first ball out of my bag. Hitting power is excellent, I am very impressed and happy with this ball. Hope this helps.
