Hey there TW posters, so if you haven’t read a previous thread I posted about stringing, the story is that the mains on my racket snapped halfway through one of my friend’s stringjobs. It broke near the top of the frame, so I guess it’s the grommets that are messed up. What I’m wondering is, Can bad grommets ruin strings? And around what tension do polys break for you? If it helps the mains in my racket were supposed to be unique big hitter blue, strung at 57. Another one of my friends told me that his polys break around 60 lbs, so I’m wondering if the high tension could be the cause for string breakage.
