For SiJ and everyday carry, I've shrunk down my XT-10 to fit in a Lowepro TLZ 20, one of the smallest bags the maker has. Fotasy grip - mostly for the forehand projection, but eventually I will benefit from the Arca-Swiss plate, an EF-20 flash (which works amazingly well at close ranges) and one of the lenses that will fit in it. Still heavier than I like, but compared to the years of equipment I've come and gone, it's about as small as it's ever been. Debating a used X70, but I can't live without an eye-level viewfinder.
SiJ is a good exercise without too many constraints, which is just as well. 60 hour workweeks since just before the holiday break and an endless string of real-life demands seem to be piling up. I plan my shooting around the AM going into work, it's just too dark by the time I get out, and too dangerous given road conditions, to be wandering about to bag a drive-by shot.
