If U we’re going to the Caribbean I say go with the AGMs. One of the best characteristics of AGM is that they will accept a very high rate of charge so you should replace your alternator to a 100amp +. If you are just cruising NA and alongside most times then in my view stick with the flooded cell.

Right now I have the old analog rocker switch and I would go/add a digital one that would show the current load. I always like the thought of knowing how much current you are drawing "right now". I added a remote panel monitor for the charger when I replaced it so I have some sort of monitor but would be nice to know current draw.
