For once I would like to be held down long enough were my men are slumped on the deck plates and I open the oxygen tanks and open CO2 absorbant waiting out the DD....maybe even get the message, 'we are out of air...' Watch my battery level slowly diminish. Make that ultimate Skipper decision.....stay down a bit longer and hang on or duke it out on the surface. If you can create this effect....you will be my hero
Just don't make all the DD tough as nails
