Wow, you saw some tarpon? That's really cool. I fished South Andros for my trips. Saw one permit on one trip and no tarpon. The camp/guides were set up for bones so the other species weren't really keyed on.
I hear you on escaping the dreary NW during the winter months, exactly the same time I escaped the SAD.
Don't know if you were on a purely fishing trip or fishing added on to a vacation trip, but if you do a trip for purely fishing, you might look at Kiritimati/Christmas island. Right on the equator, plenty of sunshine and plenty of fishing. In my opinion, the Bahamas is mainly focused on bonefish, CXI is like fishing in a saltwater aquarium. Triggerfish, plenty of bonefish (generally smaller than you would find in the Bahamas), milkfish, GT's, Wahoo offshore.
Accommodations are a bit more rustic than most places in the Bahamas, travel as I am sure you aware of is a bit limited. But the fishing is amazing....
May your 2020 fishing year be just as good!
