I tested the Quadro Twist (black 1.26) and Hexagon X (red 1.25) in two Wilson Blade Pro V8 18x20 racquets strung at 47lbs. Both sets were on the racquets for about 10 hours of play time before conducting the test. The criteria was:
1. Comfort: Simply how it feels when the ball contacts the string bed (very subjective)
2. Control: Based on hitting smaller targets (20 balls in drill)
3. Spin-friendly: Based on the height of the ball bounce (20 balls in drill)
4. Power: Trying to hit lower, penetrating shots (20 balls in drill)
All testing was with a ball machine to eliminate variability from a hitting partner.
1. Comfort: The Quadro Twist was more comfortable.
2. Control: Quadro Twist = 18 and Hexagon X = 15
3. Spin-friendly: Quadro Twist = 17 and Hexagon X = 15
4. Power: Quadro Twist = 8 and Hexagon X = 11
The least accurate was related to Power as I was personally struggling with this aspect of my game...Not the fault of the strings.
Based on this, and the fact that both strings were playing well at the 10 hour mark, I'll be ditching the Head Velocity MLT and using the Quadro Twist. But, I also enjoyed the Hexagon X!
