I am going to Little Cayman for a week in late August. Although a fairly new diver (about 25 dives in the last 9 months, not counting when I was certified originally in 1972), I have a fairly good consumption rate and reasonable bouyancy. I passed my AOW last weekend (with no dillusions that it makes me an "Advanced Diver"). I try to keep the danglies in tight, and stay off everything. I will only get 3-6 more dives in (all in Catalina) before the trip. What should I concentrate on working on before I go: more bouyancy drills, air control, something else or nothing and just get more comfortable diving?
