'seems' being the operative word here... if there are coonies to be had, using a reg for 1 minute is equally enough as would one hour? To me it is all in the mind.... we all swim in all sorts of stuff..... yet we crinch at using a mouthpiece someone else has used before.Web Monkey:Same as always, however the thought of using someone else's mouthpiece for a minute during an emergency ascent somehow seems less disgusting than using it for an hour.

But each to their own. I am not knocking it... just trying to understand and see it from that side.
