The new Edge series features a low RG symmetric core matched with two unique coverstock formulations to deliver outstanding performance options at an affordable price. The Edge Dark Purple Solid combines our new Relativity Control Solid coverstock with our proven Edge low RG symmetrical core providing mid-lane control and consistency. The Edge Dark Purple Solid delivers mid-lane control with a smooth and continuous backend motion on medium oil lane conditions. The Edge Dark Purple Solid can be drilled using the standard drilling techniques developed for symmetric core bowling balls. At Brunswick, the unique core shape of each individual ball is used for weights from 14 to 16 pounds. This approach to lightweight ball engineering provides bowlers with consistent ball reaction characteristics across this weight range. At 12 and 13 pounds, Brunswick uses a generic core shape with a RG-differential that is close enough to the 14 to 16 pound shape so the same drilling instructions can be used.
