Hey Everyone,

I am about to take the plunge and purchase the Sigma (Canon mount) 120-300 F2.8 OS (hopefully I can get them to send one to me first to evaluate). It looks like the best deal for the money right now for me. I definitely need longer glass and I cannot afford what I think will be an absurd amount of cash for the 200-400 that is coming out (my guess is that it will be double if Nikon's 200-400 is any indicator).

Now - for the dilemma...a bag. I am looking at the Think Tank bag series, but I am not sold on it. What I need is a camera bag that will hold:

Two SLRs (w grips)
300mm lens
28-70 lens
16-35 lens
70-200 lens
flash
filters
laptop

I think that I can get away with this as a travel bag. Any ideas as alternatives?

James
