Since I bought the Defiant Edge, I have really liked the RotoGrip Line. I have purchased the Wrecker, then the Totally Defiant (Replaced my chipped up Edge) and Deranged. Yesterday I bought the Scream for Drier lanes.
Interestingly enough, All of the balls seemed to hook about the same for me. All of them are OOB 1500 and Polish. I was playing around with my old C300 Outburst and had it at 3000 no polish and was having some problems at one of the houses because of dry lanes. I put polish over the 3000 and the ball went much further down the lane. This struck me as a "DUH!" moment, so I have decided to modify the finish on all of my RotoGrip balls to: Totally Defiant-1000/Polish Deranged-1500/Polish Wrecker-2000/Polish Scream-3000/polish.
I guess my question to everyone, have you had to modify the surface of OOB balls to get them to act the way they were advertised. In other words, a dry lane ball acting like a dry lane ball instead of a hook monster? For me it has little to do with my speed because I am about 14.5 at the pins with 350 revs and all of the OOB roto balls hook the same for me.
