Please do; I'm interested in understanding these reasons. The main one I can think of is that at that pressure, those things just don't hold all that much air. I used up almost all of mine yesterday, pre-charging a 20 gal. household water pressure tank to 28 psi. That wouldn't translate into much ballast-blowing, at all. Besides, those always make me uneasy by the time they get up to 120.
