Vince,

I do understand the nice feeling of having the extra gas there, and it really makes sense for rebreather bailout. Hauling full cylinders in and out of the cave you dive frequently makes no sence. I do not think the Source Nouveau T is a good spot. There is already alot of tore up clay behind the rock where stages and scooters get dropped. Finding a good place to leave a bottle after the Elbow is going to be tough. I would never plan my dive relying on the cached cylinders, but seeing them will provide a margine of comfort.

Let me know what you decide,

Mark
