I would say it doesn't really matter which way you think of him.
I'm not sure why we view being called an assembler vs. a builder/maker as a bad thing. His cues, by today's standards, probably don't even play that good. They are desirably because you can't get them anymore, and because he was the best at one point or another. No matter which way you think of him, he made a good product, that people wanted, and still want BADLY.
Does anyone know if he had the ability to build his own blanks? I would chalk it up this way if he did. Keith can BUILD an amazing cue, with a gazillion points that he cut, fit and designed himself. He also ASSEMBLES sneaky petes, plain jains, with small custom touches. He is in my eyes a definite BUILDER of cues, because he can do both. I would say the same of George if this is the case. (I would assume it is.)
Either way at the end of the day, his basic cues still sell for over $5k, and whether he was an "assembler" or "builder/maker" seems VERY irrelevant...
Best,
Justin
