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

I always like to have my launch lugs free to spin.
And prefer tubular nylon shock cords...

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...
