Nearby surplus store had these pretty cheap, but I'd assume that they
don't have a normal stock of it.

Yeah, Payton and Kurt, curious to your source when you buy large quantity Kevlar…

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...
