I bought one for my Mezz United butt and it actually improved my game. Noticeably. So I got another one for my D series McDermott. They are well made and the hit is just perfect. I can't say anything bad about them. $169 each.
I prefer Brunswick Centennial balls to the Super Aramith Pro Cup balls. Just my opinion of course. I don't use the cue ball that came with the Centennials, I use a measle ball.
