Thanks for this great info. I called my LDS (Pacific Wilderderness) and they said that only for the first hydro period is the + 10% rating allowed, afterwards they would only fill to 2250. That would only give me 2250/2475 *71.2 = 65 cu feet, which is not enough. I can't really ask someone to break the law for me. Transfilling from my HP tanks I would lose 15cu ft from my big tank making it effectively an 80, especially since the HP tanks are often underfilled a bit.

Another two issues are, changing to a Pro Valve is another cost of some $80, and the narrower tank means the tank bands have to be adjusted from my HP100 each time I change tanks.

So I'm thinking of getting the XS HP80, which Roger has in stock for $290. The short length of this tank may not be an issue for me since I'm only 5'6" tall.

If the tank is in current hydro with the + next to the current hydro, then it can be legally filled to the 10% overfill. Your LDS is ripping you off / misinformed.
