I have a similar set up and use the UD 35, together with the optional straps that allow me to use it as a backpack. It is very comfortable and loads quite a lot of gear for its tiny size. I typically travel with three lenses, such as Zeiss 21ZE, Zeiss 35/2ZE, Canon 135L. Taking only two lenses will allow me to fit all computer accessories I need in the camera compartement.
And I do not even use the front pouch...
