Thanks for all the advice!
My first show with these is on Tuesday, and there will be 4 tapers, so it's a good time to experiment a little (I'm usually flying solo). Matisyahu at the Crystal Ballroom. I'll try pointing at the stacks, which is probably around 60deg, and if I can DINa, and NOS.
As far as what I like--I'm not a huge fan of crowd noise, which is why I'm trying these hypers. I prefer the SBD-AUD matrix, in which case I want ambience in the AUD, but for AUD only, I want to cut the noise, and still get decent stereo.
