Bailout gas.....how much is enough?

[matt t.]

I will start this out saying that I am NOT a CCR diver. I do dive regularily with several CCR divers that dive several different units, and I am familiar with their features and what to do in case of trouble. For the most part I agree with the mixes and amounts of bailout gas they carry (obviously they will vary depending on the dive). I'm curious how other CCR divers are planning their bailout scenarios as far as gas amounts and mixes. What I'm seeing 1st hand and reading on dive reports is that the majority of CCR divers don't carry enough bailout gas. I don't believe in "team" bailout gas do to the nature of the bigger dives being done and the need to be mostly self sufficient. I'd like to hear from some CCR divers and what they might take along as bailout (and even diluent) on a given dive. Discuss...
