I'm currently musing about this myself for next season - dual 6 volt GC-2s or dual 12 volt G31s to replace my aging G27 but right now I'm leaning towards G31s, may even replace my single circuit Blue Sea disconnect switch with an m-Series 6007 so I can use 'em any way I want, paralleled or sequentially.
