When I was hunting for a break cue it was suggest to me to swap out the Sonic tip that comes with the Mezz PB-G. I bought the cue, and left the tip on. I'm not motovated in the slightest to swap it out for something else.
As far as comparibles... The only other CF breakers I've hit are the BK-Rush and Jacoby Black-out. I have no idea what was on the Jacoby, but on the two different examples of the BK-Rush I tried. One had the predator stock tip, whatever that is, and the other had a White Diamond. I perfer the white diamond over the predator stock. I'd lso say that the white diamond hit closely enough to the Mezz sonic that there is no difference. That said, you can generate more spin with the white diamond then the sonic. I'm not a fan of CB action the white diamond provides.
If I need something more than minimal CB action for whatever reason I'll use my player.
