I use a Domke F2 bag with a Caden insert for carrying a small kit. The insert allows laying the camera with lens, lcd, up with 1-2 lenses on each side.
It may help if you tell us how you carry and shoot. For instance, I generally use a backpack on the passenger seat of my car for quick access.
Many of the new bags being sold today do not work well with older school, heavy lenses and camera bodies. (I won't admit how many bags, or parts their of renting my closet space.)
