Track has designed the all new 503C is to be an improved version of the original 505C. What can you expect from the new 5 Series C ball? It has more length and an even more controllable ball motion at the breakpoint. From tournament bowlers to the average league player, this ball will undoubtedly be the first ball out of the bag. This beautiful Purple/Blue/White Pearl ball in its out of the box 4000 sanded and Factory Finish polished state is designed for medium to dry lanes. Are looking to use it in a larger volume of oil? No problem, just adjust the surface to a 2000 scuffed surface. You will then gain five more boards of hook for the average player; some may see even more. You will notice with the new Packman core the RG and differential have been raised by a significant amount. This will allow the ball to get further down the lane, but have more strength off the back of the pattern for better entry angle and pin carry. The all-new Gen 4C pearl coverstock is also stronger than the Gen 3 used on the 505C. The surface has not been adjusted between the two balls. What we have created is a ball that utilizes a stronger core and cover combination, but keeping the ultimate amount of control for higher scoring on the most challenging lane conditions. Each new ball from Track will include a microfiber cleaning pouch with instructions on its use. We feel this is a great addition in order to help our customers maintain their performance products.
