Comments: I used these strings in my Head racquets which have the internal holes. Love the feel of this string.
Excellent in all respects. However, it is not for the average player who still hits off the sweet spot regularly. As long as you are a solid
sweet spot connector, the string will last you for a reasonable period, otherwise it will snap at the place where it touches the frame. I
believe the 16 is a more durable string, but I haven't used it yet. I suspect it won't have the feel of the 18 or 17 though. Overall, I am
hooked to this string and would recommend it to all players.
