Currently have 2-12v 7ear old batteries that appear to be getting weak. Am thinking of replacing with 2-6v GC batteries (or maybe 4). Anyone have experience or real world review of moving to t...

I think if you went for a comparison chart that showed pounds of battery per amp/hour you'd find that 6v golf cart batteries have the advantage. If I added up 4 100ah 12v batteries vs 4 235ah 6v batteries you'll be ahead with the 6's and also use less space and right at the same weight.
Sorry but that is a common fallacy. Looking at specs it seems that for batteries of roughly the same size and weight, the 6 v seems much better. That is because the amp draw is based on 6 v, not 12v. If in your example you have 2 235 AH 6 volt batteries, you only get 235 AH total for both batteries wired for 12 volts.
If you compare size of batteries, typically 6 v batteries will take up much more space than the equivalent 12 v batteries. The weight will be about the same.
