Wisdom? Here?...Yeah Delvil's throat is a nice dive, it's WAY far south on reef, a pretty deep dive you can go +100'. the last time i did it in Sept. the visabl. was reall wierd. very poor at the surface to about 25'-30' then it cleared up. we didn't see too much sea life. but the swim thru was cool.
Currents can vary, depending on time of year, weather conditions, ect. I usually am there April-May or late Aug. early Sept. The currents are very gentle most of the time. If I'm taking pictures I can usually turn my head facing it and gently kick and hover over my subject.
We did make a night dive on this last trip where the current was REALLY strong but it was kind of fun flying through the water like Superman. You had to look fast to see anything because it went by like you were doing 20m.p.h. in a car and looking down at the side of the road. That is the only time I have experienced anything like that though.
Ditto on Deliala, Paradise reef although very shallow is always full of life, any of the wall dives are cool, I like to swim out over the deep blue and just hover there for a while, kind of freaks some people out, but I like it.
We usually let the DM's make suggestions for sites. they dive the place every day and know what are the best that particular week.
Really, I don't think there is a "bad" dive site there, it's all beautiful!!!!!!!!!
have a great trip and happy diving!!!
