Here's how I did mine...with coated Kevlar, K&S aluminum tubing, and electricians crimpers. The alum tubing is just big enough to get the strand through 3 times. I loop it through the connector, then come back through it again, then come back again for the final time. If you practice, the way you rig will help when you have to get that final tension, just before crimping.
The final adjustment is where the eyelets come into play. If you installed correctly, it should only take about 3 or so turns of the eyelets. The kevlar does not stretch either.
