I think the question "what tank should I use" is null since the 4B exists.

The real question you should be asking is "how will I fill this thing in less than 5 minutes". Because airguns SUCK at RoF.

Frankly, you should just make a springer. They're the standard to which all others are compared anyway and airguns far too frequently have to have many things done to them to keep them within regulation.
