It's the standard loadout with Adaptability down to 2, Feedback, Anti-pursuits and Intelligence agent.
I like having both Bump master and Bus at same PS since that opens up some nice plays.
Also unlike Manaroo the Bump master likes to get into the middle of things and contributes more direct damage, as well as draws some fire. With both Scout and Bus blocking, they can cause huge problems for the opponent to get out of the mess, which is the perfect time for Fenn to zoom in for the killing blow.
With PTL/AT/title Fenn the list is on 98 points currently, so I think there is some room for experimentation and tuning. Also the Intel agent is not strictly necessary, so that gives 3 points and potential free crew slot as well for playing with..
Those 3 points could be Dengar on the bumpmaster for some nasty R1 shots. It'd mean you'd have to change Dengar on the party bus to K4, but I think that's an acceptable change.
I think EMP device on the bus is an interesting option.
Especially with APL
