Hey Martin! Does the Cheetah Boom support a decent amount of weight say like a C stand?
It's definitely not a c-stand, it will not hold super amounts of weight.
It holds my Rovelight & Fotodiox 48" EZ Pro Octa with a counter weight just fine.
It holds my Rovelight & 47" Brolly Box even better. So it can reliably hold a good 6~8lbs no problem. But I wouldn't try 10+ lbs in the wind.
