I recently picked up the Lowepro Slingshot 300 AW. I carry a D3 with 28-70 F2.8, 70-200VR, 85 1.4, 50 1.4, SB-800, Sekonic meter and some filters, batteries and memory.
It is a sling type which I'm getting used to being able to keep it on and get at my camera while it is still on my shoulder. Getting out other lenses or supplies is a little tricky and I most often will put the bag down for that as you risk dropping things.
I like it a lot. The only thing that took getting used to was how the sling type bags go on your sholder. Not the same as a traditional backpack.
I'll second that. I have the 200, the middle-sized version. There are three available, 100, 200 and 300 with 300 being the largest.
If you can fit all you need in the 300, it's a fantastic bag. I find mine very comfortable and despite being a "slingshot" diagonal style strap, I find it a lot more balanced and comfortable after prolonged use than a side bag.
It's also great to be able to go from "bag on my back" to shooting in about 10 seconds. It just swings round to present the opening pouch in top in front of you. Just unzip three sides and pull camera out.
Last point is it's well designed for the slightly rough terrain. There's a decent amount of padding, it has an integrated dust / rain cover which you pull out, and a couple of loops to hang water bottles or other accessories.
I have 2 bags I have found I use most, Think Tank bags and Moose Petersons MP line of bags. When I travel on vacation but want to bring everything, I take one of the before mentioned bags and stick an empty Tamrac Velocity 7 or 9 (sling type) for just carrying around things. I think the Moose Peterson MP-5 bag is my favorite although it is not for everyone. Bags are really a matter of taste (for cameras and wives!) so the best thing to do is go to a store that stocks a lot of them and spend an hour visualizing how you plan on using them. There is not right answer to your question, only a matter of personal preference. Regards, Vincent Connecticut Nikonian My Nikonians Gallery

I've used the Lowepro Slingshot 200 and 300 with my D700 and lenses and flash. I wanted a bit more room, so the 300 suits me. In addition to how the others have described the operation, when you swing it around to the front and pull the camera out, the backpack becomes a shooting platform on which you can rest your elbows when you shoot. Very cool
A little something I've picked up for this and my Domke bag is to use a Nalgene wide mouth bottle to keep odds and ends in. It fits into one of the padded cells and is an easier way to get hold of common items than fishing around in side pockets. You can also use the bottle for water - they are leakproof - it your hiking.
I just got Lowepro Fastpack 250. It's great. It should holds the gears you mentioned. Quick access to your camera, like the slingshot. And it also has a Laptop pouch. The only drawback is I feel hot after wearing it for a while. My back starts sweating after 1 hr. I was also a shoulder bag user like you are. It's a new thing that I just have to get used to.
