Karibelle:Fair enough. And you're right - there are differing degrees of flexibility in instructors, as evidenced here on scubaboard.

FWIW, as an instructor you may encounter the same sort of differences at the shop level. I teach through a couple of different shops. The first shop I ever taught through strictly uses BC/short hose configurations and mandates that all classes must be taught with this sort of setup. Fine. Their shop, their rules. I found another shop that is more in line with the gear choices that I use in my own diving, and now I can teach using bp/w/long hose setup. I do like your "changing the world" optimism, but sometimes it can be a very up-hill struggle. There can be other ways to achieve the same end.
