Great Spin and Durability!
I am a 4.0 player and found this string to be very effective for spin and control. I was auditioning inexpensive strings and was not impressed with performance nor durability - I was restringing after 12-15 playing sessions. I put this string on my racket in early June (tension: 45# because I needed power), it has lasted through ALL of my playing this summer (4 times per week) and is only beginning to notch. This makes it a no-brainer value for the price! One challenge compared to traditional strings: Be careful when stringing your racket. This string is very plastic and will kink easily if you bend it. Just avoid bending it and be cautious with each pull through. I just committed to a full reel of this string and I am so optimistic about durability that I ordered the 17 gage for additional bite!
