Q: 6. It looks like the base of the grip could be attached to a monopod. Can you confirm this?

A: The Kirk SG-QRV2 Support Grip with Quick Release Clamp has a 1/4 female thread on the bottom. It will work with many monopods and tripods. Note, a 1/4 inch thread is not a lot. Best if used that way not to use a heavy camera with a heavy lens.

Q: 9. The adapter relies on 1/4-20 studs (from below on the original mounting plate, and from the top on the arca swiss block) to hold the entire assembly...what are the weight/torque limits on this kind of set up? How much should one trust a single 1/4-20 stud to hold big glass?

A: I would say that if you feel that way, you should trust your expensive glass to double 1/4" or single 3/8".

Q: 10. Can you change the Befree Live plate to arca-swiss?

A: No, the RC5 quick-release is integral to the BeFree Live fluid-head and not removable. If you want to us the fluid head then you'll have to use an adaptor block, like the Kirk QR-AB1QR, with the BeFree's RC5 camera plate.
