I have the wings on my phantom and ran for a while with the rear wing like you have pictured, it gave me a butt cramp (no joke) something about the way it pulled the muzzle into my right cheek cramped like crazy regardless of placement. Now I just run them in the standard format (like your front wing). The conceal-ability of an OWB holster really comes down to belt selection. I love my Volund Atlas belt for IWB wear, but it doesn't quite do the job for OWB with the raven (G26). I find my beltman bull-hide does a great job of keeping the pistol tight without having the belt be too tight. Both belts are 1.5". Also, my only complaint of my RCS is the high-ride, for my body type, my love handles push out the top of the slide, a lower ride would be awesome, I run my IWB fairly low and the curve of the grip contours right into my love handle and it disappears. For OWB I have to wear a baggier shirt or jacket, which is awesome in the winter/spring/late fall.
