^^ Depends how you are running. I clamp most of the time rather than using a stand, and I use both the Manfrotto quick release and the super depending on the situation. For a horizontal surface (e.g., tabletop) the quick release is much better. For a vertical surface (e.g., a post), I like to use the superclamp, then run an extension bar out of it. Sometimes I attach a Manfrotto 099B 7' pole to that and have a lot of height and nothing on the floor. Or I just run the mics right off of the extension.
Generally if I can find a vertical surface I prefer that as I find it a little easier to adjust the alignment of the mics that way. But this comes with knowing your venues.
Also, I should add, for the OP's benefit, make sure you are careful with clamps in general (your post makes it sound like the thing went flying "into the ether" from a balcony rail into the crowd, but maybe I read it wrong). If you aren't, you could injure somebody, not to mention your gear or somebody else's gear, by not being sure the clamp is firm. When I am in any situation where there is even a chance the clamp could fall and hurt somebody or something, I also try to use a DJ safety cable. Venues seem to appreciate that. Just a thought. Good luck - I find clamping a lot more hassle-free than guarding a stand, despite being a little tougher to set up sometimes.
