Don't you just love it when someone says that nothing is worth anything if they personnally don't like it. (Or can't afford it) (Or haven't tried it.) (Or woke up with a thorn in their paw.)
    (C.F. Martin's from the 70's.) What are these pundits credentials to make such sweeping statements?

Analogy(s) coming: (place your tongues in your cheek)
   Any banjo pickers who use anything other than animal skin on their pots are committing crimes against all that's holy. No one can make good music on a plastic skin. No one. (Recreated snippets from the 40's and 50's). Good thing that crazy fad died out and everyone stuck with natural hide.

And let's get back to turtle hunting for the only kind of flatpicks an honest folkie will use.

And while we're at it, search the alley for a stray cat. Nylon and metal strings are abominations too.

And you had better be sure that the finish on your guitar is made with the crushed shells of beetles (no, not Ringo) and not of johnny-come-lately polywhosis crap).
