Deja vu!!! You are correct, what you described is not tech. I refer to a
dive like this: Trained tech diver chooses the following profile. He/she is at a nice
quarry and the diver wants to go to the bottom,140 ft. His back gas is 32%. hmm
can't breathe that there. So Stage 26% for the bottom and diver also brings
a 50/50 to switch to at 70 all the while staying out of deco but still direct
access is available. Symantics? you gave a nice def but it doesn't cover dives
similar to what is described. A definition that covers all but recreational cave
diving: a dive that requires multiple bottles with switches.

Ah yes, the typical Scubaboard symantics police. Diving a bottom stage w/o deco in OW is not technical diving. Switching the gas mix on a NDL dive seems silly to me, but do what you want. While it may not be a traditional form of technical diving, you are assuming unnecessary risks without the training you would recieve in advanced nitrox or a similar course. However, neither of these fall into the definition that I posted so I don't really see the point of your response.
UCFDiver- Granted, there are some generally accepted exceptions to the hard overhead rule (e.g. recreational cavern and wreck) but it is just as easy to get yourself in deep doodoo 30 feet inside a cave/wreck as it is 2000ft back without the proper training, and the accident analysis supports it, so you need to decide how to approach that. I was trying to give a general definition of technical diving. You can point out exceptions to the rule all day long, but diving in an overhead (properly) is the most basic definition I can think of.
