Whoa! I wouldnt put a full monolight on that stand! Not if youre intending to also have it hold a modifier! That was why I suggested the Elinchrom Quadra! Its lighter than a 580EX II and about the only "higher powered" strobe Id trust on that stand!
i should have made myself clearer. I am using the Nikon SB28s with the Pixel TD 383 packs on these guys.
I am going to build a custom sandbag that weighs 3 lbs to help keep it on the ground. what do you guys think? 3 lbs or 5 lbs?
I'll post a picture of it here when i finish!
