I had to shine the rsp alot to calm it down, box finish is very very strong in oil, even shined it cuts through carrydown very well. I just got Epic last night i am leaving work early tomorrow to try it on some oil, since my league tomorrow is 2nd shift and my first shift league is tuesday nights.
Tomorrow on medium oil i will be comparing Rotogrip Epic, RSp, Silver streak SE, Dynothane Pure energy , Hammer Hawg Wild so it will be interesting to see head to head what handles the mediums better without too much carrydown.
My best luck with medium/heavy with carrydown is swing a Hammer HAwg drilled 4 x 4 pin below finger line, i can swing this ball like i have hand but really dont.
