George, I think this list is part of the problem. You can read all the posts you want, look at all the videos, web pages you want and nothing comes close to you standing there in your rig with Andrew telling you that you are a walking CF as he rips crap off your harness and cranks the straps down tight. His lecture, demo and training on the concepts of what, exactly, buoyancy control is and the very logical means to achieve it is worth the price of admission alone. You may think you are DIR but you are not until you go through a DIR fundamentals class and "pass." Only one of our group of 10 did and we thought we were doing a pretty good job. DIR is not just gear, it is a skill set for survival under water. This is missed by most people I fear.
