The size, amount of air, weight, boyancy and price all seem to be right. Thanks for the input.
Pretty much the perfect all-around tank.

Neutral Al.80s are pretty pointless, IMO. Too heavy (on land) for the amount of air you get, by far, and you're less likely to get a decent fill since no one thinks to pump an aluminum tank up to 3300, unless they *think* they're being generous.

Al.80:
2800psi=72cf
2900psi=75cf
3000psi=77.4cf
3100psi=80cf (overfill, dangerous to Al)
3200psi=83cf (overfill, dangerous to Al)
3300psi=85cf (overfill, dangerous to Al)

Al.80N
2800psi=66cf
2900psi=68cf
3000psi=70cf
3100psi=73cf
3200psi=75cf
3300psi=77.4cf
3400psi=80cf (overfill, dangerous to Al)

HP100:
2800psi=81cf
2900psi=84cf
3000psi=87cf
3100psi=90cf
3200psi=93cf
3300psi=96cf
3400psi=99cf
3442psi=100cf
3500psi=102cf (slight overfill, not dangerous to steel)
3600psi=105cf (slight overfill, not dangerous to steel)
Great Info! My husband got talked into 2 NAL80's and we are looking to replace them with the steel 100's just because of the pain of re-doing straps if you switch to different tanks....
