1. You're right on the resonator banjo because it is probably the most versatile banjo out there. It's the perfect banjo for Scruggs-style (and other three-finger picking). I saw a list recently of all the well-known old-timey clawhammer players who used resonator banjos (e.g., Grandpa Jones). If you lose the fifth string, they're perfect for four-string banjo styles, too.
2. Vega history is interesting. Around 1969, Vega was sold to Martin. In about 1979, Martin sold Vega to the Galaxy Trading Co. and Galaxy made Vegas off-shore. Collectors call them VINOS (Vega In Name Only). Greg bought the Vega name and it again signifies high-quality banjos.
3. For long-necks, I'd love to see a comparison between the Vega PS-5, the Ode and a Gibson RB-180. The Gibson intrigues me because it is an open-back banjo with the Masterone tone ring. The Gibson RB-180 is probably a lot rarer than the Pete Seeger longneck but I don't thing it commands nearly the price of a Pete Seeger model.
4. Just curious, Mark, but what was wrong the the Vega longneck the B4 had?
5. If you like Ode banjos, you have to read this history of the company. Chuck Ogsbury sounds like quite a character.
