Instead of the sister clips,learn how to tie a sheet bend. Very simple knot to tie.similar to a bowline.I'm assuming you have a long line(hoist or painter) attached to a shorter line(luff tension) attached to a wire? The long line is just used for hoisting so get something small and cheap. The short line is used to adjust the jib luff,get something low or no stretch. The sheet bend is used to tie two similar or disimilar (size&material) lines together.I've been using this ever since my line frayed and I had to replace my sister clips...............



Have Fun Mike
