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.
