I was excited to play this string because it was nearly off the charts on spin potential. Plus it is fairly stiff, square shaped, and had numbers that showed it to have good tension maintenance. All of my boxes were checked with this one.
Well, I will start by saying that this is a very firm string... probably one of the firmest strings that I can remember playing with. If you want dwell time or comfort or feel, then look elsewhere. If you want control and consistency, then maybe check it out.
Because of the firmness, comfort was just ok and touch/feel was fairly low. Rackets and strings don't bother my joints very often, but my shoulder really didn't like serving with this. But the funny thing was that I served GREAT with this string.
Although very firm, it had a nice crisp feel that I enjoy. Control was outstanding, spin was better than average, and power was in the medium range for a polyester. With slow swing speeds, I found it to feel somewhat lifeless, but it comes alive the faster you swing.
I put about 8 hours on this string between singles and doubles. It played fairly consistent over time. Somewhere in the middle, I thought it became a little more powerful (but not in a bad springy way), and then at the end it started to go dead (less crisp, less power, more uncomfortable). But overall, it had good tension maintenance.
My favorite thing about this string was serving. I could just hit bombs with it wherever I wanted, but unfortunately my shoulder wasn't a huge fan. Volleys was my least favorite things about this string, because of its lack of touch. Groundstrokes were good, but I was really left wanting more dwell time.
Summary: very firm, great control, good tension maintenance, below average comfort
