Pretty new to this but had a great couple of weekends away so far - one of them at the Welsh Ride Thing.
I've got a Wildcat seat and bar harness and a Revelate small framebag. "Modular sleeping system" TM (bivvy bag, sleeping bag and liner) plus poles goes on the bars. Shelter and some stove bits go in the seat pack. Tools, tubes, miscellaneous heavy bits go in the framebag. Clothes go in a rucsac along with a bladder and snacks.
Tried an Alpkit bar harness but didn't work on my bike (soon to appear on the classifieds ) - would be fine with a taller front end. Bit more on this thread .... http://singletrackworld.com/forum/topic/bikepacking-colour-choice-poll-help-me-decide
Improvements? I'm going for a bigger bag on the bars (up from 8l to 13l). Looking for a secure side entry bottle cage so I can get a bit more weight off my back. Later on will probably look for a full frame bag but that can wait.
Now the obligatory photos:
