My wife (5 ft) and I (5'11") dive as a team, which means helping each other gear up. She uses 4/5 of the air I do, so often she'll just rent a smaller cylinder. Dive shops around here will rent AL63s and AL50s in addition to the AL80s so she'll go for one of those. Of course, we stay pretty shallow (~30 ft) when diving locally. If we are going deeper, she'll dive an equal sized tank since she's my redundant air supply. I want to eventually buy some steel tanks (I'm thinking HP80 for my wife and LP85, LP95, or HP100 for myself) so we can drop some of the lead weight. Cold water diving is hard work. Honestly, the discomfort of wearing thick wetsuits is far worse for my wife than lugging heavy gear.
