It seems that from reviews, the 2-ply leather belts without sandwiched stiffeners are preferred. I wonder if the cheaper kydex stiffened belts such as those from Looper or 511 have problems with the inner stiffener breaking from flexing at the point of contact with buckle tongue and frame. I would be interested to see members' experience with plastic stiffened belts. It seems that constant bending to fasten the belts might eventually break the stiffener.
