Tecnifibre X-ONE Biphase 12.2 m

One downside is it might last three matches, thats...View More about it. I am a 4.5 player with a big serve, clocked at 115mph..not bad for a 52yr old guy.

I don't like these strings. I usually use Wilson Champion Choice but thought I would try something less expensive. Now I will go back to the expensive strings. It makes a big difference for me.
