after what others have recommended, it will be 2 trips:Are you planning on carrying three tanks out in a single trip as well? After the dive I'm usually sufficiently tired or sufficiently on gassed that I'd probably prefer several trips with less weight.
I can give a +1 for the Kubi bag; it keeps my hands free so I can fall better.
#1 two tanks
#2 one tank +rest of the gear
