Joerg,
I have done a similar set-up on my XCR, except I used a 2L O2 bottle on the left hip similar to an Argon bottle instead of behind.
Great minds think alike...

I was thinking about the 2L O2, and it would be more than sufficient for the dive. However, you see the hose of my OC-bailout O2-reg routed down the inside of the right counterlung on the last pic. It has a shutoff valve to prevent accidental gas loss, and the thought being that why carry gas that you can't use in case of a OC bailout situation. This actually saved my bacon on one occasion. So I'll probably stay with 3 liters, but I will definately change to a steel cylinder. Do you have experience with non-inverted mounting?
