I bowled on it tonight, i used my Gravity shift drilled pin to the right of my ring finger MB next to thumb, and my Rapid fire pearl , pin under ring cg above thumb, this ball has Negitive side weight and 3/4 oz thumb weight. I shot 219 233 190 170...I saw two trasitions, oil carried down, started to go long with both balls, leaving 2 8 10s... second it dried up as expected. The gravity worked really good as well as the rapid fire, i was standing on 15 hitting 4 and shot really well. From I need a ball that will clear the heads better and have more back end, I would consider a Rapid fire Pearl with a 5" pin to pap drilling, above the fingers.. A Street rod pearl, same drill, Or A Polished street rod solid... Also a spit fire if I can still get one, because that ball was really good playing out side.
