The combination of Topspin Cyber Blue 17L mains (1.22 gauge; 225 lbs/in stiffness; 18.17 lbs tension loss) with Klip Kicker 17 (1.24 gauge; 190 lbs/in stiffness; 11.68 lbs tension loss) = excellent value for a hybrid. Both are available in reels at an economical price so the cost to string one hybrid racquet is around $3.64 ($2.36 for the Cyber Blue main and $1.28 for the Klip Kicker cross). Both are thin -- 17L and 17 gauge strings -- offering good bite and spin, while the Klip Kicker further softens the Cyber Blue mains. No arm pain, lots of bite, powerful, yet you can still take some pretty big cuts and keep the ball in the court. Plus the blue mains and gold crosses = UCLA Bruin colors!!
