VB...there's not many old codder's left these day's, but the one's I know are master of quite a few things..u gotta stop hangin around those that came over the bridge 30 years ago.
my definition of a master is someone like stan gibbs/ danny p,,,many different plug styles to their credit that still work today and that many of us copy in one form or another..
A person that may only have one or two styles[maybe a new shape or not] to their credit, I define as a specialist only because they haven't yet done an entire line of different shape's.
master..one who can do it all well.
specialist...one who does only a few well.
times sure have changed.
