Gauge Recommendation

Overview
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.
