Nice looking cable with colours we don't often see! I don't have paracord but I much prefer hiding the wires above Y-split in TechFlex. Yes when you touch it it is more noisy, but if your Y-split is high/low enough they won't touch your cheek. The TechFlex helps the cable to stay relatively stiffer at that region so it isn't yanking when I move my head around. However when I used wires+heatshrink at that region I experienced what you were describing.
