I have done a bit of shooting on video as well as part of a routine while rebuilding my form this winter.
I would first of all get rid of that quiver. Worst thing to have on there if accuracy is your concern. You talk about getting so technical with your setup sometimes, but then question using a BT release and now are hesitant to take a bow mounted quiver off...........use the right tool for the job......nomsayin? Don't use counterweights as a bandaid for something like that quiver. You will end up creating more problems and headaches than it's worth.
There are a LOT of other options out there that work as well or better for storing your arrows. I have a kwikee quiver mounted to the waist strap on my hunting pack, looks just like the setup Michael Waddell uses and is just perfect. It also helps to keep my huntingbow balanced.
If you want to start messing with counter weights, etc.........go to a shop that will have them in stock so you can screw them on and play with them to get the right setup. I als would HIGHLY recommend visiting an AEP booth at a local show/shoot if you can make the time, Nunzio is awesome and will let you bring your setup in and play with everything so you can shoot it to make sure it is right before your done. This isn't the kind of thing you want to order off the internet unless you know exactly what you want. Quality stabilizer/counterweights/v-bars aren't cheap if you end up with the wrong stuff. I myself am waiting to raise the funding for Cartel's new deluxe adjustable v-bar, and 10" doinker carbon elite side bars with adjustable dawg weights for them in an attempt to add more mass weight to the bow and to help get the mass weight away from riser to help limit range of movement.
