switching to two 6 volt batteries?

I'm about to replace my two AF1150 batteries. They're currently Interstate Deep Cycle 12 volts wired in parallel.
I'm thinking of going with two 6Volt golf cart batteries. Sam's sells the Duracell EGC2 for 150 bucks. Specs:
20 amp hour rate: 230
5 amp hour rate:174
Battery electrolyte composition: acid
Battery end type: top post
Battery purpose: deep cycle
BCI group size: GC2
Freight class: 65
Minutes at 25 amps: 448
Minutes at 75 amps: 120
Terminal type: DIN
Volts: six

I was thinking that with the 2 two wired in series, I'd be better off on the Amp Hour rating. Any opinions?

Thanks as always
