The voyager exp and xt wings are a great happy medium. They are rated at 32lbs lift and are a good size to work with a tall 12L or AL80 tank. The 32lbs lift ensures the diver, diving a single tank, will have enough lift capacity regardless of their exposure suit and weight configuration, and gives an extra margin should you need to support another diver at the surface due to an equipment failure or a rescue. The newer (as of a couple years ago) voyager wings come with a bungee system to help retract the wing when it is deflated, it is unnecessary, but does work....I have a voyager exp without the bungee system and a voyager xt with the bungee system.
