With my 120s I am seldom coming out of the water with under 1000 psi and the extra weight of a 130 would not change that. I have no desire to twin up my 120s because they would be too tough on my knees and I doubt I want to spend 4 hrs at 40’ for the extra work. My daughter uses Al80s and always has more air than me after a dive. Bigger would serve her no purpose.Yeah, but, there is no such thing as having too much gas left at the end of a dive
The OP has more plans than experience and may find volume is not the only criteria for choosing a tank size.
