Bare with me fellas on the techinical stuff and ill give my views, mine is drilled pin just right& under ring finger,cg is kicked right, weight hole is is fairly low. Balldriller said this is to get the ball into a roll sooner because of my ballspeed,18-20 mph. I've used it twice in league at a house that is known 4 a lot of oil,741 & 760. Are the results so far. Mine does not start up too soon even with the pin down, I will say this it does not stop once it starts left. 2 guys on my Friday team using taboos were complaining about carrydown around the 3rd frame of 2nd game,the x just kept plowing through. Love this ball, love the whole line.
