I've fitted the NH damper and recommend it. I've dropped the forks 25mm and have stiffer custom springs and Traxxion cartridge emulators up front. It's a simple install and looks the part. The front is transformed. the NH damper is fairly basic with only 6 settings but it's quite adequate for the Thrux.
As for the fork brace: I don't believe you need it on the Thrux unless you fit significantly improved brakes like a 6 pot. (not just better pads).
