Can you beat the ghost? If you are worrying about your break but you can't beat the ghost, don't invest money into the break rack or a new break cue. Why bother worrying about your break if you can't do crap about it after it happens? I just wish I bet against people that put every bit of time into their break but didn't care about their game. OH WOW, GREAT BREAK! *two shots later* thanks for the run out, but dang that was a great break!
*edit* oh, btw, to answer your question, you already have a break cue. run the ghost, stop worrying about how awesome your break is, win much more
