For day hikes/climbs up into more extreme altitudes and rocks, mostly in the Eastern Sierra, so if you've been there, or just seen it from the 395, you'll know the conditions I'm talking about. Carrying: Tripod Various rectangular filters GH2 14-45, 20mm, 40-150 possibly 7-14. Canon 7d at least three lenses for that Rokkor 135mm f2 and 200mm 3.5 adapter small bit of cleaning gear Leatherman and various other small tools. It's got to be backpack-style, as sling-type bag drive me nuts after 1/2 or so, and most of the travel will involve steep inclines and possibly class 3 type hand-grabbing, etc.... Anyone?
I don't have any specific recommendations for you, but if you dig through this thread, I'm sure you'll find something that would suit you. I've had good luck with Tamrac and LowePro bags.
Yeah that thread is a bit unwieldy, but it does contain a lot of useful recommendations if you have the time to sift through it.
My equipment list is fairly similar to yours. I use a Lowepro Flipside 400AW. It carries my 7D, 300/4 + 1.4x, 17-50/2.8, 11-16/2.8, GH2 + 100-300, 14-140, Zoom H4n, Hyperdrive, 580EX flash, batteries for everything and Singhray filters. There's a tripod holder as well. The harness system is comfortable for all-day hikes, and you can access most of your equipment without removing the backpack, simply slide it around to the front. If I need to carry even more stuff, then its the Lowepro NatureTrekker II, just barely airline legal, but I used that for my 120-300/2.8 + 1Dm2 plus other stuff. The harness on this is even better, and the whole thing is weather-sealed. I often have 40-50 lbs of equipment in this.

I love F-stop Gear packs; I currently use the Guru. A medium insert carries my D300 rig easily, and I just got a small insert for the E-M5 system. It's expensive, but is a well made internal frame pack. Lots of attachment points for a tripod, internal sleeve for a laptop or hydration bladder (the bag has vents and loops for the hose) and tons of well thought out features. It's more comfortable than any of the Kata or Lowepro packs I've had, and there's been a few.
