Black Code in short
Tecnifibre Black Code is a co-poly with pentagonal profile for spin and Thermocore technology for comfort. "Dangerous in the hands of an aggressive baseliner who likes to control the point with heavy spin." The 5-sided profile provides powerful snapback for spin generation while Thermocore uses heating and cooling phases to soften the string. Playtesters found it "soft, plush and very comfortable for a polyester string" with muted impact feel that doesn't send jarring vibrations on off-center hits. Great value shaped poly.
Revolve Spin in short
Revolve Spin is a five-sided co-polyester string with two "wow" factors: spin and control. It's a niche string for big hitters who like ripping the felt off the ball and watching their shots land on a dime. The pentagonal shape bites the ball at contact for excellent spin generation. Quite firm and low powered, which is perfect for advanced players because it gives them the needed control to execute their most powerful strokes. At just $8-10 per set, it's one of the best value shaped polys on the market.
