I haven't tried it myself, but if I was going to I'd start with the large tweed.
Assuming that the large tweed is based on a Fender Bassman (which was originally a bass amp, it was just 'adopted' by guitarists) that seems like it could be a goer. I'd probably change the mic to the condenser model and move it back from the speaker for a mellower tone (depending on musical style of course - if you play punk or metal you might be inclined to do the opposite).
I've also heard of people having success with playing bass through Orange OR-120 and OD-120 amps. Assuming that the Sunshine Stack is based on one of those, that might be good for a grittier sound.
Other than that the old axiom 'use your ears' is good - if it sounds good it is good so try them all!!
I got a fender jazz bass with passive pickups. It was the only left handed bass in the shop I went to which made my decision really easy haha. I ended up buying the ampeg plug from ik multimedia. Sounds good.
