Got this ball for my birthday, 14 lb, oob finish, pin drilled between bridge, i consider myself a stroker, with med revs and slow to med speed, 198 avg. i bowl on wood lanes with guardian. 1st 2 weeks of league i was able to break 500. The third nite (last mon) i tried a different shot, from 15 to about 7, and shot 216, 257, and 269 for a nice 742. this ball is stronger than i thought, gets thru heads great, then seeks the dry, and goes left, and for the price it is well worth getting one.
