I'm not sure if I'm sold on R4S or the Iron Cross core. I'd like to see the R4S formulation on the Centripetal Control core (IQ Tours) and the Iron Cross with an R2S cover.
I've had the Fight since it came out and I've gone back and forth on it. For me it's been one of the least versatile balls I've had. However I did shoot 300 with it on a 44 house shot and it rolled fairly well on Kegel's Highway to Hell pattern. To me that shows the cover is really strong
