Great build... I just ordered some CXB3590's today, I'll definitely be going with solid core at the ideal connectors, I had the same issue with the BJB connectors on my reef LED setup, they needed to either be tinned or solid core wire to make a really good connection.
As for hanging these hunks of aluminum, I'm using a hanging kit from the company that I bought my DIY LED stuff for on my aquarium. A little expensive, but really worth it IMO. I can easily raise the lights up or down, and then if they're not sitting flat I can move them front to back as well and lock it in at that setting.

Here's how they look on my heatsink...
Used the same hangers over my old reef tank with a ridiculously heavy T5 fixture...
