Yeah I've read some reviews on the Shure S15A stand. A few people had issues with the adjustments on the telescoping sections. In another thread on here, someone said their Manfrotto aluminum stand fell apart piece by piece over time. Whatever I get, I need it to arrive by Saturday December 26th at the latest. B&H has a big discount on 3-day shipping, so I'll probably order from them.
I've bought some pretty expensive studio gear over the years, so $150 for a mic stand isn't a big deal for me. I'm not rich or anything, just saying...
Also, apparently the SP C4 mics now come with a pretty nice stereo bar. So if I order those, I may not need the Shure A27M for now. I've got to decide on all this stuff and place my order(s) today. If I try the Omni-Mid-Side technique, I will be mounting 1 Royer SF-12 (I've got the Royer shockmount for it too) and 1 AKG 414. I'm pretty sure the A27M will accomodate that configuration. It would be the Royer on bottom with the AKG on top, in what looks similar to a Blumlein setup.
