Doesn't get much more fun (and optional) then Caedus with Boba Merc Lobot and and uggie. Leave out the MTB for even more fun.
Boba (without the cunning) will miss way more then you like...that is always fun. Also trying to do anything NR in 150 is certaintly fun especially if you try to fit Kyle BM in your squad.
The ultimate in fun for me is Kazdan, Qui-gon JM, Quinlon infiltrator, and Ki-Adi. You start with minor init control, no door control and very low activations and if the reserves never happen then you should be a great target for the noobies and teach them why the afformentioned is important. If you are playing gambit for points then if you do get reserves then it is even harder for you cause you are giving your opponent so much more chances at getting points.
The down side is having to carry around the reserves.
