I agree Larry, that is an option. My fear on this approach being sure to check the A/S clamp regularly and wonder whether the QD option is safer. Should I be paranoid?
The Arca-Swiss system of plates and platforms is a "QD" or "quick detach" or "QR/quick release" system. Wimberley is just one of dozens of manufacturers who make products that are Arca-Swiss QR compatible. (Note: Arca-Swiss also makes other products.)
Let me make sure I understand what you're asking....
First, as I understand it, you have a Wimberley lens plate on the tripod mounting foot of your lens. One or more screws hold that A/S plate in place.
Then it sounds as if you're attaching a carrying strap to that lens plate via a 1/4" hole drilled in it (some A/S camera and lens plates provide that).
Now you are wondering if you should instead use a "platform" on the end of the strap, to more easily attach it to the plate on the lens?
And if you do that, you're wondering whether to use the type of platform that has a screw knob to tighten, or the type that uses a lever?
Frankly, I would paranoid! I'd never rely on any part of this system to attach a carrying strap! If I understand correctly what you are trying to do, it means a single point of connection, with multiple possible points of failure. The plate attaches to the lens, the strap attaches to the plate... two possible points of failure. Or, the plate attached to the lens, the quick release platform attached to the plate, the strap attached to the QR platform... three possible points of failure. The entire weight of the camera and lens supported by three or four threads in an aluminum plate?
I use straps that attach to the lugs on my cameras instead. My two largest lenses also have lugs and straps installed. All my straps are Op/Tech and each has its own quick release buckles. This allows me to remove most of the carrying strap, leaving just a couple short pieces on the camera or lens. Note: I use their Velcro safety devices on the QR buckles as a precaution, although this means they're no longer "quick release". Each strap has two attachment points... and none of the attachment points are screws or knobs or levers that might be loosened accidentally. The straps on my two lenses are adjusted for length to match the straps on the camera, so that I can put both straps on my shoulder when carrying them... four points of connection.
