I run 860HR on my 3 Diamond Bar Boxes. I have 12 teams that play Mon.-Thurs. nights, Tourneys every other Sat. from Nov.-May, free pool every Sun. all day, and average 375-400 paid games a month, league players practice for free Mon.-Thurs., and I get 2 years out of my cloth. The cloth isn't ragged after 2 years either, that's just the schedule we follow. Our tables are cleaned a min. 2x's weekly and the balls are run through the Diamond Polisher every other day. A bit of maintenance goes a long way. Brian.
