Backpacks with internal frame?

[tvphotog]

I have a 5D2 with several lenses and lites, accessories. Can you tell me which backpacks, even medium sized ones, have an internal frame with good weight distribution?

The Lowepro Pro Trekker AW II and Super-Trekker AW II have internal frames...try the Lowepro website for more details. The Pro Trekker would be more of a "medium-sized" pack...the Super-Trekker much larger.

All the F-stop backpacks have a frame.

The Kinesis journeyman has an internal frame and is the one I use (mount my TT modules in it).
