Ken,
That is amazing. Really. It sounds as if I am now, where you were 9 months ago. I've gotten to the point where I'm comfortable with my current setup. I've been diving at just about every opportunity I've had in the past several months, and my skills have been getting a lot better, but after having read a ton about DIR configuration, I've been wanting to make the switch.
Your trials and tribulations that you have documented will come in handy. I've documented them for future reference, as I'm sure to go through similar experiences in the coming months. I never expected gear to transform me instantly into a "super" diver (I know as I tried this with my golf game, but to no avail), but I view this as a step towards making diving a safer and more enjoyable sport.
When I first started diving, I had no idea of the existence of DIR, and had it not been for the board, I would probably still know nothing about it. And one thing's for sure -- lots of work and practice will ultimately make me a better diver.
Now off to find an Oxycheq dealer.....
