Anyone mounted an SMH-10 on the AFX FX-39? I've had my helmet for a few days and gotten pretty psyched about it, but then I went to install the SMH-10 (earbud clamp, FWIW) and realized that the bottom plastic trim on the helmet prevents getting the clamp unit between the shell and the EPS foam. Furthermore, the shape of the helmet does not provide much in the way of surface area for the adhesive adapter. Anyone already solved this problem? I was thinking that I could notch the plastic trim, but it's fairly substantial and I don't want to compromise the helmet. The other possibility would seem to be a much thicker piece of adhesive to conform to the curved surface, but I'd rather have a mechanical attachment than an adhesive one if I can help it.
