I use this in my crosses with Pro Red in the mains great combo. Plenty of power and control only these strings do break after about a wk to 10 days of play.
My son is 11 and plays with this string because of the playability, control, power, and most importantly arm friendly qualities of this string. It does fray and break faster than any string I have seen. But, it is so well worth it. My son gets about 20 to 30 hours before they break. I used to only use poly string and after buying a stringer to keep up with my sons string breaking, I tried it. Wow, I was so amazed. First, the serve. Spin, check, placement, check, power, check. Groundstrokes same with the added touch of being able to drop or lob. Net was also better with angles and just great pop. I highly recommend any serious player to try this string, and you will see all of these instant improvements. Unless your Nadal, which I assume you are not, stick to this multifilament and stay away from poly.
