great stuff. As you mention Kars, 80% could be a good way to start. I told Eric at VB2008 that I had never learned to pack properly and he said that I was lucky! The impression I received was that going from pack to FRC is hard (one is used to the "full tank" feeling). I think Eric's dives are about 75% volume, and he has 8l lungs? Please correct if I am wrong.
