120 Lens Plate with screw option?

[russellsnr]

I'm looking for an extra long Arca Swiss lens plate for the Nikon 400mm f/4.5 lens but it needs to have an option to attach the BlackRapid R Sport Camera Sling Strap but still allow me to put it on my gimbal without removing the attachment ring. Thanks, Russ.

So which option is going to be terribly unbalanced? If the strap attachment is at the balance point it can't be balanced on the gimbal...
This is one advantage of the QD system.
