I'm curious to know WHY he won't build a Modern 6. Maybe I'm missing something here? It just seems that, in light of the popularity of 6's in modern music (especially in Urban Gospel) and factoring in that Roger makes, IMHO, the best combination of articulate and modern married to fat and vintage, he would absolutely shake the market at its foundation. Even if it was only a NYC option, I bet at least 10 or more TB'ers would instantly order one.
When I had my Metro M5-24, I strung it with an E-C set just to try it out, and DAMN if that C-string wasn't more musical sounding than any of the twangy C strings I've encountered on 35" scale instruments. IMO/IME of course.
I think a trip to Japan with a ton of cash is in order....
