Thanks for the compliment, Earl.
Too bad things didn't originally go as planned, but I now have the Soyuz all fixed up better than new. The crash was beneficial in identifying structural weak spots. (See Mission Control: August 11 Launch report) All the broken pieces have been reassembled and I've done a lot of internal reinforcing. I made bracing from .039 piano wire and attached it at the bottom to limit twisting of the boosters. It worked very well. The whole assembly is much more rigid.
Everything got a fresh coat of paint and I have upgraded the recovery system to 400lb. Kevlar.
All cord connections will now utilize split rings. It seems that the crash was due to the Kevlar cutting itself. I had tied small bowline knots on all the cord ends and the connected loops cut through each other when subjected to the forces of deployment. The 30" parachute that I wanted to use won't fit, so I may try two 18" and hope they don't get tangled up.
The weather here is exceptional and I want to try to fly it again soon.
