Mainzer -
I have a LevRg, 3-1/4" pin, 2-1/4 TW that I drilled 45 x 4 x 35, no X-hole.
I am pretty speed dominant compared to my low rev rate, and this ball can still grab early on me at times. It's not quite as angular as I had hoped given the layout and the current league conditions, but the ball has tremendous roll through the pins when it hooks up.
Your mileage and ball reaction may vary.
