Nope, just straight up Duralast 135. It is NOT fun to string when he kicks back during a match, let alone two in a row. Turned a 10 min on court frame into a 13 min on court frame
If you read the current blg on ATP, you'll see something that happened to him that kind of sucked. He had the wrong gauge string. Mistakes happen when product is shipped out to players, and unfortunately in this case, it happened ot him. At Roland Garros. As defending champion.
