My fellow 512er made a good showing at Nationals with 5 FOs with Crack and Weapons Guidance:

Now that is one I was considering. Swapping Howlrunner for the 'dispersed bonus' of weapons guidance means you keep fighting better for longer. The only time I tried something similar it was with everyone given Wired - not the most effective but rather amusing as the first game I played was against a swarm of tactician TLTs. The frustrated yell of "I'm just firing bloody rerolls at them!!!" was very satisfying.
