Technifibre X-ONE 17 lasts almost twice as long! I do the sweet spot.......4 MAINS and 7 CROSSES......28 stringsavers total. Face the longer direction of stringsaver with the crosses helps protect the crosses even more.........strings feel clearly at least 5 pounds tighter based on 28 stringsavers used...........string 5 pounds lighter and enjoy! Thank you MIDWEST and BABOLAT!
This is the best string saver on the market. I install them with an every other one pattern in the sweet spot area when I hybridize strings with natural gut. They prevent the mains from moving and give me extra life on the gut strings plus some added spin as a bonus. These are great!
