I haven't strung up the Composite Edge yet, but I did string up a white Head Special Edition Edge (16x18) with black grommets and no issues with the grommets. Zero cracked or shattered holes, I now have hope for the Composite Edge when I get around to it. FWIW the lettering on the side of the throat of the Special Edition Edge notes a head size of precisely 81.1 square inches. USA flag on the side and Made in USA on butt cap sticker. Graphite/fiberglass composite but no % on the mix. I wonder if that was measured from the inside or outside of the frame.
