I'm planning on adding a 2 foot section of Yale 'Cover Only' to the clutch point of our spin halyard to bulk it up. Twice it has slipped in the clutch in big puff, and much fuckuppery ensued. Is there any best practices to:  1) secure the ends to the underlying halyard? 2) smooth the ends so they enter and exit clutches, mast exits, etc clean? 3) secure the length to minimize any slipping along the length?
