Hi ergarant,
While not perfect, the flooded setting on your charge controller should work just fine.
Ideally with those batteries (in daily cycling use) you would want to bulk and absorption charge at 14.7V then float at 13.6, with NO equalization charge… all temperature compensated of course.
I'd only be concerned about the float voltage being too high for long term storage. You might choose to use the Gel setting or simply disconnect the batteries from the controller when in storage.
Here's a link to a PDF of the Odyssey Battery Technical Manual.
