I have two large softboxes, an extra-large 54" x 72" Photoflex LiteDome, and a 5' Profoto RFi Octa. Although I plan to buy some Einstein E640s for use with these, my current monolights, a Dynalite Uni400 Jr., and a Speedotron Force 10, have tension-only (as opposed to saw-toothed) tilt brackets, with baby receivers. I happen to be using Matthews' Beefy Baby rolling steel stands for these (a.k.a. "Hollywood Baby Jr." stands). I'm wondering what's the best way to keep these strobes' tilt brackets from slipping? I was thinking of just attaching a 40" extension arm to a Cartellini clamp on the light stand with another 20" extension arm as a support. I'm not sure what else I could use to "hold up" the softbox, or at which point, and to what, would I attach to the top of the softbox (if I were to support it from the top instead of the bottom), without damaging it. Now, if I were dropping these down from a boom (which I'm not), I could use a baby pin, dropped vertically from a grip head, but it's just more convenient to have these on rolling floor stands for the moment. Any ideas? What does everyone else do?
