Really dull cue designs.......any veneers or points that aren't razor sharp.......rattlesnake wraps on a great custom cue.......sloppy cue-maker signatures on custom cues but some cursive signatures are cool like Tascarella, Richard Black, Paul Mottey, etc.
Oh yeah, things I hate in a pool cue............cue-maker names/logos on cue butts which are too large.........sloppy inlays & ring work............ floating points regardless of the cue-maker..............shafts larger than 13mm or smaller than 12.4 mm..........pool cues weighing more than 20 ounces (like my custom Runde Schon weighs).............any cue that isn't straight........and every seller that bullshits you that their cue is straight but actually wasn't.
