i strung up my Vantage VT321 with 17g of this. I played with my friend yesterday who I have been playing weekly for the last 6 months. He said my kick serve had more kick than usual.. I previously had Pro's Pro Cyber Power 17g/OGSM 16 in it. We did play on a different court than usual but both are both hard courts with the same wear...
Anyhow. I like the string. I was really getting some good control with it. We played a set of doubles of our set of singles with a couple of young hard hitting bucks. I'm 40 while my friend is in his 50's..I'll play with it more and provide feedback..
