Rental tanks in Greece

[Grey Goose]

hey folks, heading to Greece on Sunday. What kind of tank can I expect at a rental shop. I'd like to get an understanding of the tanks characteristics (volume, pressure, steel vs. Aluminum) for weighting and for dive planning calculations. Leaving my Bp/w and drysuit home and renting a BCD and wetsuit so weighting may be a little messed up anyways until I can do a weight check.
Thx

In 2012 I dove on Santorini and Mykonos and they both used AL 80s (12l) with yoke values....typical tourist tank. But we did very basic dives so that is expected.

Thanks oldbear. I'm diving close to these islands ( Sifnos). I wasn't expecting Al, but given that is what I dive with, good news if it works out this way. I assume they are in bar?
