I, too, have one of those Rove lights. They are very inexpensive (which is nice when you only need it rarely), convenient (stringing power can be an interesting exercise at times, even indoors), and heavier than all get out. When I stick that thing 9 feet up in the air with a good, "normal" light stand and with a small soft box I get nervous.
I feel a lot more comfortable using a C-stand with about two 15 lbs (7.5 kg?) sandbags. That seems secure enough for me, but then I rarely shoot with wind blowing my stuff around.
