this ball is laid out with the pin next to the ring finger, the cg towards the grip center and the mass bias indicator just below the thumbhole---no hole. it is wetsanded 2,000 grit and highly polished with brunswicks factory finish high gloss polish. i tried different lines/releases/speeds during shadow balls and noticed that my "a" game worked the best----a down and in shot around 8-9, a end over end type roll, about 17mph(appx.). this was one of those evenings you only have several times in your life. game #1, one tripped 4, the next 9 high flush. ringing 10/spare--289. game #2, the first 6 high flush, a mixer, the next three high flush. major pull, 6 pin/spare...289. game #3, flat 10/spare, the next five high flush, flat 10/spare, strikeout high flush---269...847. this is a mixed league and the other team were throwing plastic balls right down the 4th arrow. my teammates were all throwing polished resin balls down and in anywhere from 5 to 12.
