Q: 5. What do I need to attach a monolight to the grip head? Some sort of pin?

A: If you are trying to attach the monolight to the griphead at the end of the extension arm yes you need a pin. I just use a 5/8 x6 bolt from the hardware store. The extension are itself is 5/8 I believe so the monolight can be directly mounted to that end. Remember this is not a boom arm and you will need sandbags or other weight to help balance the weight you are hanging off the extension arm.
