you are better off with the 4 batteries over a dozen in series. Anytime you are stringing batteries together, especially in your case where you are going to be doing series / parallel strings, you are going to have a whole other world of issues to deal with.
Flooded cell batteries? First off, No you are not mounting those on your roof, they probably will end up weighing 1000 lbs by the time you get everything you want. FC's will need CONSTANT attention and cleaning. The acid fumes are going to corrode stuff, they WILL need to be protected from the weather and oh, lets not forget one other little annoying issue with lead acid cells.
When you charge and discharge them, they create HYDROGEN. Can you say BOOM ! Hindenburg anyone?
Finally, no matter how good you take care of them, how 'deep cycle' they claim to be etc, those batteries will have a life of 5 to 7 years TOPS.
They cost more, but from a maintenance standpoint, and longevity, and being able to install anywhere in any orientation, Id go with the Lithium chemistries.
Have you considered looking into used fork truck batteries? Often time you can get them VERY cheap. THey won't hold a fork lift for a full 8 hour day anymore, hence why the owner wants to be rid of them,but are PLENTY good still for a house system like you want !! They are built to last longer than a few years, and are heavy as sin, so the dirt bags wanting to steal, they are heavy enough that it'll slow the thieves down enough to give you enough time to get the shotgun and add to your compost pile to keep the taters happy !
