I really appreciate the offer but I think I'm sold on steels, and jersey it quite a distance from me.

Yes, the dead weight. If one tank physically weight, say, 10# more than another, it will be more work to move it. You might think about a 10# lead weight, suspended somehow, that you had to push through the water. It's just more weight and it might not be worthwhile.
Just to pick two tanks at random: a PST LP 95 weights 43# empty and a Worthington X7-100 weights 33#. At rated pressure both hold about the same amount of air but the PST tank weighs 10# more. One way or the other, you have to move that weight (mass) through a distance and the product of mass and distance is work.

Typed that up to make things a little easier. Didn't realize how big the LP tanks are compared to an AL80, even with their wider diameter. The 24" 100/119s are very appealing.
I've had enough time rucking in the army with a 60-100lb ruck. I don't feel like doing it when shore diving also.
That LP121 is nearly half the height of me.

Gotcha, thanks for the insight. Looks like I might end up going with the 100 after all. It's 9 lbs lighter, and more compact in general, and obviously cheaper. Plus it would require more convincing to get my buddy to buy 119s as well. My dive buddy back in FL wrote me back saying she really likes the HP100s also so...

If you are going to dive with a female, you should get MUCH bigger tanks. Women just don't use air! It's embarrassing...
Seriously, I have 6 of the HP 100s and I like them a lot.

Couple of points
1. Go visit Fill Express is you are in West Palm Beach, they have all the Worthington HP tanks right there for you to look over and put your hands on.
2. HP 100's are fantastic tanks, HP 119 are also great, same height, just 8" fat.
3. Have a pair of 100s for everday diving, but consider HP 130's. For the drift diving we do down here, deeper wrecks, and lobster hunting, they are fantastic.
