K&S makes great Kevlar thread I've been using on Pull Pull for my 120 Ultra Stick, and my Magic. It is slightly more resistant to fraying than the Sullivan thread, but you still cant let it rub on anything during operation. I'm using a H9 pull pull wheel on one end, works perfectly, and on the other, 4-40 screw eyes. I tied miniature slip knots through the eyes, centered, and tightened them. Then secured the knot with a drop of thin CA. I put a small peice of blue shrinkwrap around this to preserve the knot, and to make it look better...
Hope this helps
