Awesome! I miss my trips to PR for tarpon and bones. You're doing it right man, exploring up inside.
I fished La Paraguera and Boqueron Bay and the lagoon at SJ. LP was outstanding when I was there, the action was insane. B/B needed a boat as well as SJ but I did not (yet) explore the countless lagoons as you have, although I really wanted to I jumped over to Culebra.
That is a whole different fishery... I found the bonefishing to be similar to the Keys, rather than copious shoals of 2-3# fish there are less dense packs often containing some really big bones.
Also some giant permit as well as oceanic tarpon, jacks, etc.
