It is really come down to things that vary for each person. Being comfortable in the water is probably 90% of it. I buddied up with this lady some years back, nobody wanted her. I was solo but decided to do the honorable thing for once

. She was about as close to 100% body fat as I have ever seen! And was one of the most controlled and disciplined divers I have encountered yet. Her trim was perfect, she was dialed in and completely at home in the water. I had a wonderful several days buddy diving with her. She had a camera, I had a camera and we were still finning along taking pics when all the rest where on the boat waiting on us. Well, anecdotal stories mean nothing but, yeah, comfort in the water, completely relaxed, she was THE zen diver!
