Urban unpacked Q's
Recently, I found myself at a new exit which I found to be a bit low for my FF tastes so I decided to change over to an unpacked jump. Luckily for my slack-unpacked-ass there was plenty of room for me to take my rig off and change over, but there are also a couple of other interesting exits in the area that are pretty much unpacked/SL only, for me. I suppose what I'm really looking for is setup ideas to be able to climb conveniently (hopefully with standard deployment system intact,) yet still have a relatively easy way to convert to unpacked, with low-ish exposure to those not involved, while sitting on a narrow catwalk without taking the container off. In case it matters, I jump velcro.
P.S. I always carry a couple of lengths of break cord with me, now.

Thanks in advance.
