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.
