Problem is I don't shoot at one location. I move around. It is pain to pack everything or lift everything you want to move 10-15 feet. With rollers I can just roll around. And the casters have wheel for bracking so I can't imagine stands walking away.
Bobby, if i did location work and moved my set up around quite a bit i would customize a 2 wheeled hand dolly
i would have air tires and use a vagabond to weigh it down on the front and on the backside i would have adjustable legs that pivot out over the wheels like the turtle stand
next i would have rings on the uprights i could insert the adjustable riser to mount my strobe
my modifiers would sit on the front side of the cart when transporting everything
so in short basically i would combine a turtle stand to a hand dolly loaded up with what i need
