I don’t know anything about it.
But, if you want a productive answer, it’s better to ask it more subjectively, like:
Does anyone know if the bnei torah in Miami Beach use the eruv?
Or:
Would a ben torah from NY feel comfortable using the Miami Beach eruv?
And, since you probably won’t trust any answer you get anyway, (because you will get both answers), it is even better to just call a rav you trust there and ask him (subjectively, again).
