I don't really notice much of a difference in the water between 85s and hp100s.

Filled to the same 13% overpressure (3750 PSI), MP72s hold 80 cubic feet. With their thicker walls, I bet it will be easier to convince the fill technition to give me a 4500 PSI fill where they hold 98 cubic feet of gas. I'll be negative as all hell, but a redundant bouyancy device should midigate thoes risks. Anyways, I would rather get LP85s than LP66s as the 85s hold 95 cubic feet of gas at a 13% overpressure (3000 PSI). Additionally, you see my profile picture. I just bought all of that, so I've got to get rid of alot of used gear before I start buying expensive cylinders.Small in what sense?
I really like how you put "voodoo gas" on your cylinders. However, I don't like the boots. The reason being is because DIR teaches (DIR is like a cult, really) that you don't need boots as you should either be wearing the rig or you should have them layed down. Plus that an extra $20 you can put towards more useful gear.Here's the picture of my HP 80s

Do you lay down on them to don?
3750 is already an overfill. You will be hard pressed to get that especially given the age of whatever MP72 cylinder you bring in and the fill stations opinions of it, justified or not. You will not be getting a 4500 psi fill so I hope you are not factoring that capacity into your planning.Filled to the same 13% overpressure (3750 PSI), MP72s hold 80 cubic feet.

No, it's a simple balancing act. The arguement is that you shouldn't leave your gear standing up unattended. When you are donning, they are attended and thus can be stood up. That would be funny though.
I usually doff on a paved slope, standing up, and the boots make that easier. I lay them down whenever I leave them.
