The compressablility of your undersuit should make no difference. You're still going to be putting gas into your drysuit and if you put just enough in to take off the squeeze, you will always have the same amount of lift in your suit. Or am I wrong?
The 55lb wing was designed for high capacity cylinders in mind, specifically the Pressed Steel 104 or larger. 104s are 8" in diameter as opposed to the Faber 12L cylinder which are 7" in diameter. This lack of width means that there is more wing sticking out of the side of the cylinders which then 'wrap' around the cylinders. It makes the rear dump higher up and harder to reach, and because of the wrapping it can mean that the gas in the wing can be higher than the top of the wing where the corrugated dump is, making it hard to dump there as well.
If you are diving properly horizontally the wrap of the wing will make it very difficult to dump from the corrugated dump of the wing. If you're seahorsing it's easy as the top of the wing is the highest point, so one could argue that you have to have good technique to make it difficult to dump from a 55lb wing on twin 12s...
As for lifting a diver - weren't you taught to always use their buoyancy? That way if you let go of them you aren't going to go up like a polaris missile and they aren't going to sink. The chance of a buddy falling unconcious and losing both buoyancy compensators is so unlikely as to not really be worth putting up with the inconvenience of the 55lb wing for.
