I have a PD Capture Plate on the bottom of each camera body plus on the tripod socket of the 300mm f4 and 40-150mm f2.8. (The tripod mounts are rotated so the bottom of the mounts are facing 90° left. This makes the body lie with the bottom against my body.) I have the plastic Anchors attached to each of these Capture Plates plus the left side strap mount of each camera. There's a permanently mounted hand strap on the right, shutter button side of the camera body.
When shooting with a lens without a tripod mount, I use Anchor links to the camera Capture Plate and the Anchor on the left side of the body. If I have either of the long lenses mounted, the ends of the strap attach to the Capture Plates so the body lugs don't carry any of the weight.
When carrying the 150-400mm f4.5 I use Anchors on the 2 built-in mounting points of the tripod collar and carry all of the lens/camera weight with a Slide Lite strap. It makes changing everything pretty quick and easy.
