either my cue or sometimes a house cue, at one spot i play i found one i like so i use it, but usually my playing cue, my break is weak so it really dosent matter
I used to have a predator bk, and I loved it, but I got rid of it. Since almost all of my pool playing is 1-pocket, it just didn't make sense to have a cue I'd only use once every couple of months. On the rare times I get into a 9-ball or 10-ball game I just use a house cue to break.
