Major Taylor - he was a black American sprinter from the early part of the 20th century and lent his name to the adjustable stem. I think you meant to say 'Major Nicholls', didn't you
I think a lot of 'better' builders master the art of not over-heating the tubes around the lugs when brazing. If they are over-heated it affects their resiliance, strength etc. and this may affect the way in which the frame 'rides'. In the end though, it's a very subjective thing. The same frame can feel completely different to different riders.
It also helps if the builder builds frames straight and in track as well!
I think what denotes a 'master' builder is the little details and the standard of 'finishing off' (filing etc.). A perfectly good structurally sound frame can look diabolical if care isn't taken over the final steps.
Today is the yesterday of tomorrow.
