Originally posted by capote the suggested 294 looks good… i can do 170. but i'm a little thrown off by the weight... or maybe it's not that big a difference. i do nighttime shooting with my k-7 and 35mm da or 55mm da* but i'm always in places i'm not allowed to be in that have a lot of things i can trip over and not very steady terrain and lots of police and security that want to chase me out so… that's why i feel like every pound matters.
Don't forget the 25.00 mail-in rebate, which brings it down to 145.00. If you are doing stealth shots, tripod may not be suitable for you. Instead, look for a monopod and a shoulder brace, a shoulder stock or beanbags. Lightweight gear you mention above could probably use a Gorilla pod quite effectively as well. I was under the impression that you wanted a reliable, robust tripod on a budget that you don't end up replacing every few years, I think the 294 could deliver that.
Edit: If you have to be quick on your feet, quick release the camera and throw it in the bag, fold up the legs, throw it on your shoulder and run. Even quicker, fold up the legs throw it over your shoulder (camera still attached) and run. Collapse the legs while running.
