Hello, Im using ashaway microlegend xl and powergut 65 strings. I string them to 9-12 kgs and they last 1-10 games max. Usually strings break from the middle main strings, grommets are okay. What can I do to prevent breakings? I once had some Nanogy 9x string and that lasted a bit longer, but playability was quite bad. I had same breaking problems with bg 65 & 80.
