Just wondering if anyone has brought a portable bounce/fill kit into the BW with you? Was it worth the weight and portage annoyances? Any specific brand or style that you liked?

I have seen the ones that pop up like those tents that you throw and they self set-up (which seem to pack nicely) but I am unsure if it would be worth bringing in.

I don't bring in anything to bounce light of off, but do bring in my strobist stuff so I can shoot wireless flash off camera.

I bring a few pieces of alumimum foil for helping filling shadows on macro shots.

Nope, I try to keep it light weight and compact.
