Been using the LE for a while now, and I'm still working out what works best for me. My tripod is a Gitzo 1320mk2, which has been working great; solid, simple, no complaints whatsoever. I've been using a Gitzo 1377m ball head, with no quick release, which is NOT working very well for me. It's a PITA to level, and it's a PITA to mount the camera on the tripod. I'm looking more along the lines of a Bogen 3047/3057/329RC4 3-way head, with a QR.
My "bag" is actually a trunk, a Calumet Deluxe Molded Large Format Case. Got it fairly cheaply on ebay. It's a horse of a trunk, and it's very bulky and heavy, possibly heavier than the entirety of the gear I keep inside it, I was noticing this past weekend while out shooting. The upsides: it holds a LOT of stuff, and there isn't much chance of anything inside being hurt. Put some wheels under it, like a wheeled luggage cart or a dolly, and it's perfectly satisfactory for urban work, which is pretty much all I do these days. It's definitely not the most efficient way to haul my gear, but it works.
