Difference in weighting between Alu & Steel doubles

[WhiteSands]

Hello,
How much weight can I typically remove when moving from aluminum 11L doubles to 12.2L steel doubles?

I use around 14lbs with the alu doubles in a drysuit with FE Arctic undergarments. Unfortunately where I'm going the logistics won't allow me to do a weight check before the dive.

Thanks.

Bands are the same, manifold is the same.
AL80s are +4 lbs
BUT
a steel 12 could be almost anything. a 200bar 12 is not the same as a 300bar 12
a PST 80 is nothing like a Faber 85 which is nothing like a worthington 85

What country are these 12L steels in and what is their rated pressure?
