Second on the Wingman. Used the Mustang before, didn't like it. For one thing, it felt pretty big. The inflator is at a bad location. As you pull yourself up the boat, the inflator is like a bump that stops you. I worry about tearing the inflator to bladder attachment if I drag my weight over the inflator it. So then you have to lift your body over the inflator. That adds another maneuvering step to re-entry.
Got the Wingman after that, and is perfect. It felt very small. The inflator is in the back, so no interference. Has a pocket to put my car keys.
