Need some help picking a backpack please

At the moment I have

Gripped 7d (grip could be removed of course)
70-200 2.8
Sigma 10-20
Sigma 30 1.4
580EXII
Couple cheaper flashes

Will hopefully also have a 5d soon

Was given a Tamrac Expedition 8x for christmas but I think I'm going to return it. It is just too big

I'm using an Expedition 6x with similar type of equipment. Ordered a 7x, but was way too big once I received it.

Yea the 6x won't fit my 15" Macbook, which I forgot to mention

The Lowepro backpacks are pretty handy. Shame is that they don't have the name of the product marked on it just the lowepro logo. I bought mine from the local camerstore, threw away all the labels and now I can't check what "name" the bag has. I think its the larger AW pack though. Suits me perfectly.

Does it look ridiculous when you wear it? The 8x would look just outrageous if I wore it around haha
