uggg, no! Tie a better knot. I forbid electrical tape on knots or bunjis on our team. You just never know when you need to undo something and there's nothing worse than trying to find the start of the piece of tape on the head of the kite while you're trying to balance yourself bouncing up and down through waves when your spin halyard is dorked up when a trapeze bunji breaks and both trap lines decide to knit themselves with your kite halyard.
