Hi. I don't know anything about this topic, but probably your best source of info might be Sunset Sammy. If you look just below your post, there are a couple of current reports from him, as he is currently (possibly still, not sure) in Carriacou on a land based trip, and access to internet may be sporadic. You might want to search also for posts by him, for possible trip reports from that area. Hopefully he will respond here, but it may be a few days, if he is still there in Carriacou.
