I do a modified pool of epoxy, in that I take fiberglass cloth, about a 2" x 2" section, sometimes bigger or smaller as the airframe dictates. I make a "U" in the cord, then tack it to the cloth with some CA. I then mix epoxy laminate resin and wet it out, then place some wax or parchment paper over the cloth. Lastly, I either lay on the side or inflate a balloon in the airframe press to press the airframe. After the epoxy cures, remove the balloon and/or paper. Using this method I have never had a failure at this area of the rocket.

CAVEAT: watch that the place you attach your cord gives sufficient room for the nose cone shoulder so that there is no interference.

Also, you may want to consider braided Kevlar. It is strong, and heat resistant and will likely be the last part of the recovery train to fail. I know that Gus (a.k.a, Steve) had a post a few months back on where to get it.
