Wow!!! Well yes apparently I should have researched better before doing all of that work. Geeesh. I really focused on the importance of the coop being secure and didn't pay enough attention to the run. It's on my list now to reinforce/replace. Thanks so much for the heads up.
Have a suggestion for you if you are up for it. Take a bunch of pictures of your coop and run, create a thread and invite suggestions. Unfortunately, it is harder to retro-fit a setup than to build it initially, but you will likely get multiple good ideas that you can use. My first setup has been pretty good, but I've definitely learned enough here that when it is time to rebuild, I will present the design here before building.
