I think the Y split is one of the more challenging parts of a cable to execute cleanly. It would be nice if we could compile a small catalogue of different ways people execute their splits. Whether that be with a bought product, or craftyness with shrink wrap. Lets see them. My first cable. Super basic. Just taped the techflex tightly and put one piece of regular 2:1 shrink on it. Might use adhesive shrink when i redo it.
