You can safely underfill a HP tank (that is about the same physical size, yet lighter) to get the same amount of gas a fully filled LP tank of similar dimensions gets you.
So if you plan on overfilling a LP for higher capacity, you should be comparing a LP80 to a HP100 and a LP95 to a HP120.

Um, sort of depends on what pressure you intend to overfill to, doesn't it? I usually push my LPs to 3000, but sometimes to 3600. The question should simply be to what pressure can you overfill (and what pressure do you want). For me, it's all about capacity, not pressure. |
Excellent point
Rainer, as was the other about the cost of LP v HP tanks. I'm just trying to make the OP aware that they should be looking at more than just the cf capacity of a tank.
Anytime someone wants to buy a tank, especially if its their first tank, they need to look at many aspects of the tanks considered. I think the first should be the intended use of the tank vs how it'll likely actually be used. Then lots of other factors come in, such as the cf capacity, the physical dimensions & weight, HP v LP, cost, tanks buoancy haracteristics, availability of fills, ability to grow with it, physical size of diver, air comsumption rate, etc, etc
