POWER-PRO fishing line is also great. $15 for a spool at Walmart and you'll have enough cable to last the rest of your life. More abrasion-resistant than Kevlar. Easy to tie knots in. I tie a fisherman's knot at the servo arm, and also at the other end where I use a DuBro 2-56 eyebolt into a clevis. I slide the fisherman's knot to pre-tension it when I first tie it, then lock it with thin CA.

The ONLY thing I have found to be cautious of is Power-Pro will melt. I was shrinking my monokote with a heat gun, and....where'd my pullpulls go?

Kevlar does not melt.

I just hate using the little crimp sleeves on wire cables.
