Man, the weight/chambered thing vs NYC vs Metro thing has come up so many times...
FWIW, I don't think it's reasonable to put the the Metroline/ME vs NYC on common ground simply based on weight and chambering/solid alone. IMHO, that's not fair to Roger OR the Metro stuff. They're different products for different markets.
The reason Roger has to charge more for the NYC vs the non-NYC is because of all the extra time/effort put into material selection/matching, and so much more of the hands-on artisan TLC that goes into the NYC basses vs the more traditional production level non-NYC stuff (and I do NOT disrespect the non-NYC stuff with that comment).
To some, the difference is subtle, and not worth the price uplift of an NYC. Honestly, that's fair. Good for those people. They get a KILLER bass and save thousands of dollars over the NYC stuff. That's a legit WIN on every level. Period.
For others, it IS worth it, because they notice/feel the difference significantly enough, can afford it, and that makes it worth it to them. That's ALSO completely fair, and ANOTHER legit WIN on every level for them.
My point is, I don't think it's fair to either Roger/NYC or the Metro/Warwick stuff to boil everything down to an oversimplified matter of just weight, or even a figured top or not. To do that, is to ignore a lot of important things about the different products and their target markets.
IMHO!!!
