After picking up the 5J, I've been trying to find a good build for it. The jump jets made me want to get a decent size engine in it and use it for hit-and-fade tactics. This build came about from trying to maximize the available hardpoints. I've had moderate success with it, especially in the more closed in maps. It runs a bit hot, but the PPC and SRM 6 are rarely used together which helps keep the heat down.
