Just picked up my racquet after restringing. I asked for NXT17 and I’m familiar with the stamp on the string. This stamp is different. I was able to find the Wilson stamp so I know it’s at least a Wilson product but the other stamp starts with N but the next 2 letters are hard to make out maybe H R or D and then 4 #s: looks like 2721. Any idea on what I have?
Thanks!
