I suppose you are suggesting getting a tunica stretch with an ADS. I don't think I'm stepping out onto a limb by saying it's just not possible. Working the tunica takes some serious stretching or hanging, and I don't think that the intensity needed to affect the tunica could be handled for very long. Anyone else?
Can you use your ADS OS (Over the shoulder) and still have it be discreet? I would think during the colder months you cold rock this under thick clothing.
