[Mullins]

I've only played around with FRC diving, using it as a warmup technique before constant weight dives while I've been over in Egypt and the Bahamas. Despite not having much of a background in deep diving (ok I've gone reasonably deep, but in brief stints only) I adjusted pretty quickly as far as chest flexibility goes. However equalisation is what limits me. It's ok with a noseclip and mouthfill at about 5m but a lot harder with a mask. It would be interesting to try deep FRC dives but my time in deep water is so limited I can't really afford to be mucking about with a training approach that may not aid my competition diving. I'll get around to it one day.

If I start looking seriously at CNF then it might be a better way to go than inhale + packing, as I have such a huge buoyancy change that I find it hard to get off the surface without fins. I don't expect it would be too difficult to switch back and forth between the two dive strategies.
