To summarize, I prefer to use an elastic fabric shock cord that's too long. But hey, everyone's different.  . |
I'd second both these points. I also in a number of cases, especially rockets with payload sections or large nosecones, have the rocket come down in separate sections on separate chutes. Tends to solve a fair number of recoil damage problems, but more items to keep up with in the sky (though spectators like to see the 'extra' chutes).
