If your Trubor runs, I would shoot it for a season or two. Once you are in need of a back-up or want a different configuration - you will have a good idea of what your ideal gun looks like. Having owned a DVC, the real differences compared to a Trubor are mostly cosmetic.
As others have stated, the Brazos Zig Racker is awesome. While detents can be added to any racker (so as to avoid using a set screw) it's nice to have them from the get-go. Venom Customs installed my rackers, very pleased with Don's work.
