Weather hasn't been cooperating with us, and we just learned the dive op we were supposed to go out with tomorrow can't go, so it's not being a diving-intensive trip.
But back to the OP's question -- you can't read too much; you will find that various people and agencies differ on a wide spectrum of points. In surgery, we say that, if there are a bunch of different operations for a given problem, it's pretty certain that none of them works terribly well (or that one would become universal). It's the same with technical diving. You can make arguments for doing things various ways, and often the bottom line is that each decision has its good and bad points, comes from a different set of underlying assumptions, and has different implications for how you execute a dive. But knowing there are different approaches and trying to understand the reasons behind them will help you ask better questions of your instructor during your class.
