What charge mode for AGM battery?

[codemonkey]

Just received my solar panel with the intention of using it up in the paddock to charge my big, heavy AGM batteries so I no longer have to bring them back to the house to charge.

The solar controller has three modes: SLA, Flooded, or Gel. Which mode should I use for my AGM batteries?
