Anyway, what I need help with is what you could call a video "shot list" of events or "opportunities" a recreational diver could find themselves in, where having DIR skills ( such as trim and bouyancy) will make a major difference in how much fun they can have/how much adventure they can safely enjoy.
My buddy and I had a moment of navigational error in Bonaire on the second (outer) reef. 100' of water, and we're both pointing 180 degree opposite directions towards shore. So we did a free-ascent, complete with nice 10' stops starting at 50', and made it to the surface calmly. Without mid-water buoyancy skills it would have been an extremely nerve-wracking experience. It would have been even more relaxed had I, say, brought along an SMB and spool!
Not sure if that's the kind of example that you're looking for. The silty overhang sounds pretty awesome.
