I personally hate to see people kicking up the bottom. Unfortunately, it happens way too much. I use the frog kick quite a bit, but when I am just slowly cruising the reef looking at the small stuff, sculling works best. My favorite dives are shallow reefs. Although, I have experience in most types of dives that people today call technical diving. All except for the cave thing. When I was learning how to dive, it was called wreck diving, cave diving, deep diving, etc. I personally believe the name Technical Diving covers too many different types of activities to be a good name for all of them. For example, someone could be considered an experienced cave diver and wouldn't know one twit how to dive and penetrate a wreck. I can't for the life of me see why they are not fairly similar, but ask Walter about a dive on the Duane he had with an "experienced" cave diver and he can tell you a scary story.
