I drilled a Piranha Retro recently, got it for a song. 3" pin and 3.25 TW. I am a high rev and high track player with slightly above average ball speed. I set the pin about a 1/8 inch right of my ring finger and stacked the CG directly below. I shined the ball as well.
I bowled on a semi dry condition, synthetic lanes. The ball got through the heads well but pretty much burned out as it got to the pins. Needless to say I wasn't thrilled with the reaction. I normally drill with the pin directly above my ring finger and stack the CG. Would I get a better reaction by redrilling this or can someone suggest a better layout. I know the core is egg shapped with a puck on top, relatively weak from what I've heard. Any info would be appreciated.
