Camera gear (and travel) backpack advice needed

Need some advice guys.

I am planning a trip to Europe next year for a family wedding in England, and it's going to be a minimalist trip. My girlfriend and I plan on visiting a few western European countries in 3-4 week span (Ireland, Scotland and perhaps France). Luggage and clothing will be as little as possible as we intend on being quite mobile.

I need some advice on a backpacks that can hold a fair amount of clothing and accessories as well as a few bits of camera gear. Specifically, a body, two primes or small zooms, flash and, maybe, a compact tripod or monopod. Should I just use a regular backpack and stuff the camera gear in amongst the clothing, or am I missing a more useful and practical option with specific gear compartments??

Thanks.

Look at fStop bags, they seem to be in favor here for blending the functionality of a Backpack with the add-on bits of a camera bag.

Here is the Tilopa for example:

Exactly the style I was looking for... thanks for the info!

Also look at clik elite. They will have some good options as well.
