Comments: Playtest day 1 I strung it at 51.5 lbs on a Head Youtek Speed MP mains and crosses. I did moderate pre-stretch. This allowed huge spin. It had much more pop than most of the polys I have tried. I played at 40 degrees so it was cold. After 3 hours of testing minimal tension loss and minimal breakdown on the star pattern of the string. Kick serves were wonderful. feel at the net was not great, the string has to much pop. A little tighter tension might have helped with that. I did not notice any difference in elbow or shoulder pain. Would use for league and tournaments but probably hybrid with synthetic to soften it up a bit for net play in doubles. All in all suits my long topspin strokes.

Comments: Poor tension maintenance. Maybe prestretching helps.

Comments: This is a great string in terms of playability. Soft and really arm friendly. Great feel for a poly. Great power. The only negative aspect is the tension maintenance that is really really poor.

Comments: One of the best polyester-based strings on the market. Excellent power, feel and control. Would highly recommend for others to try.
