Comments: This is another great string with a nice price. Very soft on the arm. Spin is ok but not much. Durability is ok. This is good for player's battling tennis elbow. I strung a full bed at 53 lbs on a Volkl Organic V1 and 52 lbs on a Pacific X- Force.

Comments: I had major tennis elbow recently using polys, so decided to do some research to see which string would be easy on the arm, at the same time something durable, holds tension well, comfort and control. I think I found one. The feel is not as you would expect on a Natural Gut, or Synthetic, or lower gauges strings, but this would do. So far, I've strung 2 out of my 3 rackets at 55lbs full bed on my (YouTek Radical Pro). I will try next time to string the mains at 56lbs and something softer like a synthetic on the cross strings at 54 lbs to replicate the feel. After 9+ hours of heavy hitting with topspin/slices, the tension dropped down just a few pounds, but that's expected. I really like this string.

Comments: I did not like this string; very dead feeling, no sweet spot. I've used and loved Isospeed Energetic for years, and thought this would be an improvement. I'm sending them back. Im a 4.0 player.

Comments: This string holds tension very well and I'm impressed with the durability. It is more durable than some 17L or 18 gauge polyesters!!!

Comments: I love this string, it is crisp and comfortable, and keeps its tension well, better than energetic, if that is possible.
