I see that DIR diving still hasn't caught on from the few posts on this part of the forum. That is too bad, it really is a high speed low drag way to dive. No bulky jackets, outstanding regulator hose setup, and reduced weightbelt with a stainless steel backplate.

If you haven't tried it give it a shot. Halcyon, Dive Rite, Hollis, Oxycheq all make great backplate harness setups. You could even go OMS...if you had to.
