The EPIC is a revolutionary designed high performance asymmetrical ball from Roto Grip. Once again we have taken technology to a higher level with our brand new Maxiumus core. This asymmetrical weight block has an RG Differential of .050 for maximum flare potential along with a Mass Bias Differential of .024 for a spin rate of EPIC proportions.The coverstock surrounding the Maxiumus core is our aggressive Ultimate Vision solid reactive, made from the finest Grade A reactive urethane found on the market today. The EPIC was designed to give you a quicker spin rate for better mid lane, and energy retention all the way to the pit.X Blems are seconds due to a cosmetic blemish similar to an X Comp, but the specifications fall out of the 2 4 2 4 oz. range. There are a couple of areas that the ball would not meet some first quality manufacturing specifications i.e. core chip or engraving error. X Blems will have an X stamped by the serial number. The label on the box is stamped X Blem and is marked with a small red number that denotes the specific issue.NOTE Due to the limited availability of X Blems, X Comps, X Outs, and Seconds pin placement and top weight are not guaranteed.Product Type Bowling Balls
