Dennis Searing first. His cues have a Michael Jordanesque grace to them. Sadly I highly doubt I will ever be able to own one.
Tad Kohara is another one. He does the best butt designs of any cuemaker I have seen imho. He took a spot of the butt that normally has a few rings and maybe an inlay or two and turned it into a masterpiece.
I could actually go on and on so I will just list who I would buy the first week I won the lottery. Searing, TAD, Gina, Szamboti (Barry and Gus), Balabushka, Spain, Hercek, Black, Diekman, Cochran, Scruggs (used to own one), Southwest and Tascarella. That would be the first week and trust me I wouldn't stop there.
