Is that 1/8"? That's very good in small rockets. Make it extra long and you don't need no stinkin' stretchy nylon. I use it in high altitude rockets with small drogues. Takes up very little space. Rockets up to five to eight lbs are no problem.
Are you selling?

Wait.
I thought the Kevlar was heresy, and nylon was orthodox.

I always like to have my launch lugs free to spin.

The first launch of the SuperStrypi rocket
http://spaceflightnow.com/2015/11/04/air-force-declares-failure-on-super-strypi-test-launch/
failed
early in the first stage burn. Not to speculate, but
the rocket did use a rail to launch. I'm thinking
that they let the launch lugs spin instead of having
the fixed, this caused a gyroscopic progression
combined with the Corilolis effect caused flow
separation at the lugs resulting in unbalanced mach
cone development resulting in asymmetrical buffeting
on the fins causing flight instability resulting in
failure....
If they ONLY would have kept the launch lugs from
spinning the failure could have been prevented...
