Steel or Aluminum?

[lars2923]

I own steel HP100's and couldn't be happier with them. The relatively small size and negative bouyancy are nice. Naturally when I travel to faraway places I have to dive what's on the boat, and that's usually AL80's.

I own HP 100's and love then too.. BUT Papa brings up good points

The Aluminum 100's suck for one reason they fill at 3300 psi. So on a boat you get 3000 that cools to 2850psa you have a huge 80 anyway. I have both, but really like my LP95 and my LP120 both steel

I own an ALUM 100 and 80's and LP 108's and HP 100's ... As papa said, the HP's are hard to
get a good fill.. The LP are easy to get a good fill.
If I had to choose my tanks over again, I would go for the LP98's and crank them up to 2449lbs... (lol).
