Thanks for the responses.
I wouldn't be considering this at this point without the encouragement of people who do know what they're doing! So, I am told the buoyancy, trim and propulsion are all more than sufficient to start tech. But I practice this too, on every dive. I learned my first day out that I didn't like the feeling of bouncing around and not being in control of my depth, direction and speed. With that in mind, I made the conscious decision to practice at least half of every dive on basics. As a result, my trim is as horizontal as I want it to be without thinking too much about it, my finning is ok (other than back-finning which still gives me fits), and I can hold my position in the water column (+ or - a foot) for 15 or more minutes, launch a DSMB without flailing about.
I am not familiar with gear configuration. So I guess that is the question. Is there some course that will concentrate on learning how to dive with twinsets so that I have those mechanics down and integrated with the basics before adding in the additional tasks involved in the "tech" part of technical diving?
If it helps, I won't start this until May or June. Which will mean that I'll probably have an additional 60 to 80 dives under my belt before tech starts.
