What I'm saying is:
Put a strong drilling on it, and let the aspects of the design of the ball, being long with backend snap work together. To me, sounds like the length drilling isn't matching up with the cover/core for what he wants it to do.
That's what I'm looking at. I had a BW Pearl, pin over the bridge, and it was horrible for me, and I tried every option with the cover on it. Have another drilled stacked leverage right of the fingers, and it's a great ball. Kinda where he's at on his Venom.
