Camera bag suggestions 4 travel

[Prelude]

Hi all
I've read a few reviews and done a bit of research but am still dumbfounded as to which bag to get next.
I have been using a Crumpler 7 Million Dollar Home for a few years now, but after recent trip to Hong Kong, realised that it was just too one-sided heavy for me and needed something different.

I like the idea of a backpack, but not one that can be easily opened from behind (for security reasons), but also want something that is easy to access.

My gear:
-40D (possibly with grip in near future)
-24-70
-70-200 f/4 IS
-10-22
-50 1.4
-580EXII
-Manfrotto tripod

Any suggestions/advice would be welcomed. thx

Its a tough decision. Backpacks are great for comfort but harder to get things out of quickly. I took two bags to Italy with me last year, one was a Lowepro Minitrekker and the other was a Lowepro Toploader 75AW with some lens pouches. After a few days walking around with the Minitrekker on in 80° weather, my back started to get heat/sweat rashes from the combination of sweat and the backpacking rubbing my lower back. So that with the combination of the bag being hard to get into quickly made me start carrying the Toploader out during the day and only using the Minitrekker for going between hotels and in the airport.

I usually carried my 20D w/grip with the 17-55 2.8 IS on body. Then inside the Toploader 75AW was my 70-200 2.8L, 10-22mm and maybe my 24 1.4L or 85mm 1.8 in an accessory pouch attached to the bag. It was a tight fit and not the best solution, but it worked out. I was able to fit the 20D with the 17-55 2.8 IS inside the bag with the 70-200 2.8L but that was where it got really really tight.

I just purchased a Domke J3 shoulder bag to fill the void between these other two bags. My Toploader was just a little too small and I didn't want to be stuck with a backpack thats hard to get into. You may want to check out some of the new Lowepro backpacks though. I think the Fastpack series is like the Slingshot series but it has two straps like a backpacks yet opens like a Slingshot does for quick access.

Only choice is Flipside (or something like it) or the Fastpack. Both prevent easy rear access, the Flipside more so because access is against your back. There are a few reviews on here already about it and should hold what you want if you get the 300.

Thanks for the help!
