You could also try a custom sized Stealth. I ordered one, but haven’t yet received it. (Shipping from China takes ages.) I’ll be ordering another one with an experimental feature, when I’m able to. But, getting back to the pinching, if you’re too tight near the base, but fine everywhere else, try measuring yourself as you would for the normal Stealth, but also take mid-shaft, and base measurements, and convert those to Stealth sizes, and see if any deviate from your normal measure, if so, perhaps a custom fit would be right for you.
Happy Stealthing 🙂
