Actually it works well for me but you have to add zipper protection.
Thank you for your feedback John. I imagine that the shock duration is less important than the maximum force. Assuming a 10g deployment on a 3-pound rocket, the maximum force is 30 pounds, well below the cord's nominal 550 pond limit.
Heat is an issue--I remember--way back in the service--using cigarette lighters to melt the ends of para cord lengths to prevent fraying. However I imagine that the parachute itself is even more vulnerable to heat and as long as I have enough wadding to protect it, the cord may be OK.
On the other hand, as you point out, few seem to be using it, so I'm curious.

My rocket weighs 3 pounds or less, is ziperless, and goes really slow (odd-roc slow). I do have a 5/8" nylon cord from LOC, but it's 12 feet in length... seems kind of overkill.

Capn', I notice on your zipperless designs, you work hard to tie the cord to the inside of the top section. I wonder about the placement of your bulkheads--I imagine if you mount the bulkhead lower, you'd still have enough room for recovery "train," but also make it easier to tie the cord.
