You wouldn't even dive with a BP/W and long-hose setup just for the course and then go back to your old rig if you wished to afterward?That’s great, but I don’t want to dive in GUE standardised kit or with standardised procedures. I did want to do something I enjoyed, and I enjoyed DM.
The gear is only "standardized" in the sense that certain key bits of gear will be the same for all students in the course. And as I mentioned, a BP/W and long-hose reg setup are not specific to GUE; divers who trained through various other agencies, both tech divers and rec-only divers, even some who profess to dislike GUE, are using essentially the same configuration.
And although GUE teaches specific procedures, such as the step-by-step way they teach you to deploy a DSMB or share gas, I would imagine instructors with other agencies teach a specific way to do such things as well. What instructor teaches five different ways to do a task in the same class? It would confuse the student and not be an efficient use of time. For purposes of a course, I would imagine every instructor has some way they would like to see you do something, regardless of agency.
I'm getting a vibe here of some sort of (please excuse me) "standardization" paranoia, which I don't think is based on the reality of what is required of a student in a course. After the course is over, you can dive in any gear you want, in any way you want, with whomever you want, and yet your improved skills will stay with you if you continue to practice them. But nevermind GUE and Fundies--the larger point I was trying to make was that similar instruction can be found through instructors with other agencies as well.
I can't argue with, and in fact completely agree with, the desire to do something "enjoyable," and I'm sure the DM course can be enjoyable. So can other courses. My wife and I, who had hardly heard of tech diving at the time, both had a blast in Fundies. It was challenging, yet a lot of fun. Nevertheless, one thing that these intro-to-tech type courses do not attempt to do is to teach how to lead and look after other divers, and if that is the gist of what makes the DM course enjoyable to someone, then the DM course seems like an excellent route.
