"Ditching" was the primary survival technique taught in the 1950's. The later adoption of buoyancy compensation devices was (presumably) the answer to negative buoyancy emergencies where formerly the diver would be prompted to dump weights or even the entire compressed air apparatus. Moreover, as a backup or alternative to these potential problems the tanks themselves were made in such a way as to be positively buoyant when empty. That was considered to be a significant safety advantage. The day has arrived when extremely high quality and partially automated BCD's are in almost universal use. These devices are not only tools of convenience which removes some of the idiot factor in the need for dive planning but also act as safety back ups for surface flotation. Additional devices like pony bottles, "octopus" systems and various gauges provide the diver with continuous information and back up to support planning and eliminate panic situations. With all this, we are still hearing the litany about possible emergencies or "incidents" requiring the possible need to dump weight. This is getting a little crazy and it's "deja vu all over again".
 
Favorite tanks:

#1 -- HP 100's -- mine are now doubled and are great as singles and even better doubled

#2 -- HP 130's -- more gas than my doubled 72's, good weight and balance characteristics which are important for the cold water diving I do

Absolutely HATE AL 80's!!!!! What an evil tank.

Wow! That’s a powerful emotion to have towards a tank! A tank I’d gladly strap on in Hawaii!:D

I too use a HP100 and love it.
 
I prefer the HP 100's, but usually dive HP 119's just in case someone does something stupid and needs gas.

I own two X7 HP 100 and also mounted the 13 cf steel pony, for added safety in dives to 100 feet. I do a lot of shore diving in Monterey.

With students or local diving with most people, HP71s...nice and small and more than enough gas

With people with same breathing or close, or not with students....HP100 :D
Depends on the dive time though and depth
 
Bought my HP130 used and love it, on the prowl for another one. Know lot's of people with HP100's and they love them as well.

One thing to consider is if you are thinking of turning them into doubles down the road (which I am not) HP100's may be a good choice, I know a couple people about my size (5'10'/160lbs) who use double HP120/130s and the setup is soo heavy they really have no releasable weight! Myself I'm nowhere near experienced enough to feel the least bit comfortable with that idea.

Nice tank, but hard to find.

Unless it's a really really good deal, I won't buy a LP tank. It's a lot safer to underfill an HP tank than it is to overfill a LP tank. Over the life of a tank, the cost differance between, for example, an LP95 and an HP119 is insignificant and they both hold the same amount of air at he same pressure.
