I'll put in a vote for the Avenger boom and stand. I have one and have had no problem mounting a head from either my Calumet/Bowens Elite pack/head kit or the heavier Bowens head from my friend's Bowens QuadX, AND a very large softbox (18" x 60" or thereabouts). I never tried putting one of my monolights on it but I have total confidence that it would work just fine.
