Don't think anyone is going to overfill an LP tank by 50% in this neck of the woods. I hadn't realized they were talking about THAT much overfill. My main shop will go a few hundred over. Another shop nearby won't put it out the door above rated pressure; he calls it a "bomb". Don't burst valves tend to go off if you go too high?.... LDS said he has seen burst valves go just by getting too hot like in a car. (Adding 50 degrees F in a hot car on a 90 degree day would add slightly less than 10 percent to the pressure, by the way.) I have heard of plugging burst valves but that seems over the top to me. Anyway if that is the main reason for LP's, that you have to exceed their rated pressure by 50% to beat HP's in terms of gas/pound of tank, then my inclination is to stick with HP's, either 100 or 120. So many other more controllable risks in scuba, why add in a wild card like REALLY stressing out your tanks.
