I am just saying that in my dives there are many times I do not feel I HAVE to carry a canister light. Most of our deeper dives down here lately in the gulf of mexico are recon dives. We are chasing an elusive german u-boat supposedly bombed during WWII by a plane off the mouth of the Mississippi river. > > I use Barry's backup lights for backup as well...

I personally do not feel a light of any type beats a mirror, sausage, colored lift bag, etc..for full daylight. > > As far as the doubles vs. big LP singles goes, it's been my experience that > the doubles are more stable when freestanding or gearing up on a rocking > boat, and that the center of gravity with doubles is less "wishy-washy" > while I'm diving, especially with a cannister light or a stage.

Many people are afraid the o-ring will blow in a single tank configuration. Personally I don't find that much of a concern because we are using stages and further I would not do a dive with substantial deco or a deep cave dive with either a single Y or eighties setup. > Hey, I'm no player and I don't purport to be.
