are you sure it's carrydown or is your ball burning up too much energy as it goes down the lane ? if your ball speed is on the slower side your ball may be using up too much energy. if your release is too end-over-end roll it may be rolling out. but assuming there is carrydown the goliath is the most aggressive ball brunswick has ever made. it is wetsanded 400 grit from the factory----very aggressive. you will need speed, oil, spin, or loft to get it down the lane. thankfully, the particle coverstock is very user friendly. you can wetsand it finer( 800, 1,000, 2,000 grit etc.)very easily. or, if you need more length brunswicks rough buff or factory finish high gloss polish will work quite well. good luck.
