Great report. Don't let negative nancy's bother you, in any society there are many, usually called armchair quarterbacks. But, don't confuse DIR and tech diving. Many people cringe one way or the other when referred to by the wrong term. Just as there are different techniques in diving, like going inside a wreck as opposed to a cave- the thought of leaving a stage bottle anywhere on a wreck springs to mind, or diving somewhere that has vis to a place where your buddy disappears 3 feet from you. It sounds like you had a great time, we hope to have as much fun. I wish I could even write half as detailed of reports on some of my runs, but the gift of writing eludes me. BTW, there are 2 forms of penetration, within and out of the light zone. Within is taught by PADI, etc. More advanced requires much, much more training to do safely, specific to the environment. If you liked the 'swim throughs', take a course on it, as there are many techniques and ideas to use.
