Ya I think I just made up my mind.
HP100 or HP120?

I'm a little shorter than you guys (5'10"), but proportionally am also short-legged/long-waisted and I find the Worthington HP120 is d^mn near perfect for me. Sure, I don't usually need all that gas, but then there are those 120' wrecks where it's awfully nice. And they trim out so nicely!
It's also the single most efficient cylinder made in terms of dry weight vs. gas capacity.
Only thing I don't like is the fact that carrying them from the top kind of forces me to scrunch up my shoulders to keep them from dragging - and after multiple boat trips in a day, hauling them back and forth, those particular muscles sure do ache!
That said, the HP100 is certainly one versatile tank and fits nearly everyone, so if you think you'll be loaning yours out much, that might tip things in favor of the 100's.

I am 5'7"or 8" and have no problem with the HP120's. Weighed one today with 400psi at 40.5 lbs. Filled it to a hot/warm 3600psi so it should be around 3300psi when I dive and it weighed 48lbs,if that helps with your weighting.
I dont mind the extra gas,if I do a quarry dive most of the time I can do two dives on one tank.

I just hate being the first one at 1000 and it's time to turn. 
I just bought two Worthington 120's - LOVE THEM. I am 6ft and it means I don't need a weight belt as I can stuff the remaining weights into my BCD's quick release.
Sure, I don't need that capacity for local shore dives, but on deeper or wreck dives? Priceless. + what is the difference if you are carrying the weight in lead or steel?

Hmmm...I have double 100's, single 100's, and tend to use my 130's the most. You can never have to much gas, but you can have too little. Our last dive my friend with a 120 came up with 600 psi and I came up with around 850 psi. We did do a fairly long dive though.
There is also the 119 which is wider (8") and shorter.

Hey Linedog,
I have 4 HP120s, 2 Worthington and 2 PSTs, and love them! Depending where you are in Washington, I'd be more than happy to meet up for a dive and let you try one out.
Shoot me PM...
Edit: although, my suit's in the shop, and I won't have it back for a couple weeks. PM me anyway, and we can work something out.
Further edit: I also have a Worthington HP119 and a couple Faber HP100s you could try, too...

Hey Scott thanks I just might take you up on that offer.
To me (when choosing between a single 100 of 120) it is all about trim. And this is different for everyone. When diving a single I use a 100 because it trims out better for me (but may be the opposite for you) and I know I will have enough gas as I am only doing dives demanding a single. When diving doubles I use 120s because they trim out better for me as doubles and I have that extra gas for deeeeeeep dives.
If the 120s do not trim out correct for you and you as they are too long then HP steel 119 are shorter (and wider) and actually hold a little more gas than HP steel 120 (go figure).
My advise would be to try them out before you buy one.

Don't get too caught up in the length of the cylinder. I am 6'6". I used to dive single hp119's. Now I dive double 119's. I have no problem trimming them out. They feel perfect for me. IMHO, it is what you can get used to. If you find something where the price is right, go for it. High volume singles are great, just make sure that if you do decide to go to doubles, you can handle the weight of 2 high volume cylinders.
