OK! Some very interesting feelings about batteries are being shared here, and sharing is good. ;)
I think if I had 23 grand at stake, I would be very passionate. I have two ordinary Napa marine group 31s that cost a total of less than $300, and my last set of two lasted for five years with heavy camping use. They lived in my garage on the BatteryMinder when not on the trailer. So I have a lot less at stake, and I probably won't be buying a lot of extra equipment (ammeter, commercial-grade hydrometer, and manual charger). I have one of those squeeze-bulb hydrometers -- it accurately predicted that one of the cells in one of my former batteries was about to go bad, which it soon did. Good enough for an amateur setup.
However, I am very interested in re-wiring my panels with ten gauge wire, not only from the controller to the batteries but from the panel to the controller. I could then install a quick-disconnect between the panels and the controller, so that I could run my cable directly to my batteries and "boil" them. That project does not seem too daunting, even for someone with limited technical skills.
The hard part will be to figure out how much "boiling" is enough, and when to do it. There has to be a "cookbook" out there for non-experts -- if your battery has a rated capacity of X amp/hours, then you should boil it at Y volts for Z hours. I know that is not the expert way of doing things -- but there is a time and a place for lowest-common-denominator checklists and procedures.
