So I've always used 17 gauge or thicker strings, I recently put on a 1.15mm Proline II on one of my racquets to try and I love everything about it. Except my grommets are breaking in two separate places, the parts that touch the strings in the inner hoop are tearing apart. I have never had grommet problems before in the past, is this happening to anyone else or is this just a bad coincidence?
