OK, here is my review in the TW format of the Volkl Power Fiber II 16.
Stringing was pretty easy.
Tension it is strung: 50 pounds on a lockout machine full bed
Your regular string set up: Discho Microfibre 16 @ 50 pounds on a lockout
String pattern of your racquet: 16 x 18
Power (or lack there of): Higher powered multi
Feel: Not very good
Tension maintenance: Dropped each time out on court. Not a good trait for a string.
Price: $12.99/set, reel price I don't care
Overall comments and feedback: See below
General: This review will be short. When a $13 string stinks, I say quite simply "It sucks".
Serve/Return of Serve: Serves are the only highlight with this string. I served well but if the ball came back I was in trouble.
Strokes: Spin was a chore to create.
Volleys: It feels OK on volleys, nothing special.
Touch shots: Not good
Softness: Stiff for a multi string.
Tension: I don't think tension will compensate for a company that does not make good multis.
Durability: I cut it out after 4 sets of singles. This string is a "snapper". I have a feeling it would have broken in my next match. The "frayers" usually last longer than the snappers.
Movement: String movement is average for a multi meaning it moves a decent amount.
Conclusion: This is a below average multi string with a premium price. Maybe Volkl should only be considered for polyester strings.
