Dave, I *might* be up there for that show, in which case a j-disc would be great. Since I don't have a j-disc, I usually run omni's in a really wide ORTF pattern, really wide, about 160-170*. It produces very nice imaging, but I'm pretty sure a j-disc would be even sharper. If you've built one, I'd defintiely run it. Split omni's onstage in Barley's would be a little bit too chatty, I'd think.
