I shoot lots of concerts. When doing local ones, I plan on asking permission and using my SU-800 to control my SB 200s and SB 700 around the stage.
I bought a couple Manfrotto 175 F1 clamps with a ball head and flash shoe. When trailing at home, I noticed that the SB700s fit snugly, but don't actually lock in place even with the lock lever flipped. I fear that when hanging from lighting or speaker rigs, the bass may case them to back out and fall.
The Calumet version has an Arca like screw/sliding plate that tightens onto the foot.
Anyone have any experience with either? $60 vs $40 each.
Your gonna miss 100% of the shots you never take, so keep shooting.
