First time in Coz, looking forward to learning the ups and downs and diving with a bunch of you. Question: Is the water warm enough for just a shorty, or do I need the full 3mm suit? Question 2: I'm a relatively new photographer, working with an Olympus XZ-1 and the relatively low-powered UFL-1 strobe, which pretty much illuminates only within 3 feet of the subject. Are the drift currents so strong that the strobe is essentially useless? Or will there be dives where I'll have adequate hang time? (I've done drift diving before, most recently in Boynton Beach, but from some of what I read in here, Coz sounds like a giant rip tide.)
