SIRUI P-36 Kit, Aluminum Tripod Base and Adapter, SIRUI Monopod Support with Quick Release, Foldable Feet, Vertical Notch (Tripod Base and Adapter only)

Yeah, I hearya. Shooting in a con on the hoof is a completely different proposition, unless you can stake out an area to set up a mini studio or bring a friend to be your VALS. Whether it's a stand or a superclamp, carting a modifier and bracket/adapter is going to be more than you want to lug about all day. Last year, I brought my 6-section Sirui CF monopod and tripod foot for stabilizing while shooting video at panels, and that foot was way too heavy and bulky to be carting about in my bag all day with all my other stuff.
