ATTENTION! ATTENTION!
My very first 300 was with the old version and I averaged 220 in that league. Since then I have had good success with it until the lanes I bowl at scuffed up the track very badly. By that time the Rock On was discontinued. I have since purchased other equipment such as Reaction Roll and Swamp Monster and others, but nothing hit as hard and carried pins like the Rock On. Now, to my delight I have gotten back that edge with the Limited Edition Rock On and it is everything the old version was. THANK THE BOWLING GODS AT COLUMBIA 300

ROCK ON FOREVER!!!!!
