I would have to say Jack Potter of Libra cues was underrated. His cues hit terrific and I wish he still made them. I currently play with a Greg Hearn cue, he made a great playing cue as well, too bad he passed away.
Hurricane Cues out of Charleston, SC. They play great and are very reasonable on price.
Jerry Powers of Jerico Cues.....much underrated.
I agree with icantgetaroll, Hearns cues play great. Yes, I own three of them but that's why I bought them. His pointwork was fantastic. He is missed.
Oh, the Hearns cues are in my avatar actually -just not showing off the points in that pic.
He is but he does get overlooked quite a bit. His workmanship and playability are second to none IMO.
TYed Harris makes a great Cue, and IMHO is under rated!
Jeff Olney and Scott Gracio.
Their cues are nicely priced and their finishing is top notch.
