I got one of these OMS King Sized Dual Bladder. I changed the bungee with slices of innertube and I don't have any problem fully inflate this with my lungs. The wing is extremely hard before the overpressure valve starts to leak. But I think the hole damn wing is completely overkill. Who need 45 kg lift ?? I have switched to the Halcyon system and can't wait to dive it. ---------------------------------------------------------------------------- Atle Aamodt ---------- > From: Paltz, Art <Art.Paltz@R2*.CO*> > To: techdiver <techdiver@aquanaut.com>; cavers@ww*.ge*.co* > Subject: RE: Added info re three missing in WPB > Date: 19. januar 1998 22:09 > > I've got a question/suggestion.
