With polyester strings continuing to dominate the stringing spotlight it's no surprise that string manufacturers are continuously innovating and releasing new polyester strings designed to provide more spin better tension maintenance and improved feel. French string manufacturer Tecnifibre jumped back into the fray with Black Code 4S a new take on their Black Code poly that features a square profile and is designed to provide maximum spin power and durability all while offering excellent tension maintenance.
Installing Black Code 4S was actually a lot less trouble than expected. Typically geometric or textured polys can be a bear for the fingers but 4S wasn't terribly onerous even though the edges were definitely noticeable. Coil memory seemed typical for a polyester but with a little care tangles and kinks were easily avoided. As with most geometric or textured polys installing crosses comes with some risk of damage due to the sharp edges. I didn't have any issues but I'd still encourage other stringers to take their time installing crosses—especially if they're blending Black Code 4S with another softer string.
