Does anyone else use normal nylon string for shock cords? What is the general consensus on it?
From my perspective it's slightly thicker than Kevlar string, dirt cheap and available everywhere, has a reasonable test strength (130-160lbs), and tends to wick in glues and adhesives easily to make knots or attachments permanent.

I feel like I've had good luck with it as I normally build my attachments 'estes style' ahead of an extra centering ring used as a baffle / bulkhead in the front 1/3rd of the fuselage, as opposed to the higher power methods that tie Kevlar cord around the motor mount. My guess is that with the motor mount tie off approach the main driver for using Kevlar is that you're trying to ensure it holds up to repeated exposure to motor ejection charges.
