I've used it many, many times for cramped on stage applications and have had great results (IMO, of course). If I can run a split omni instead, I prefer it, but when cramped, and when the Jecklin disc is just too much of a distraction, Healy is killer.
I also LOVE using it outdoors when two tall stands aren't in the mix to run split omnis. I've had excellent results with it that way, as well. If my 7/27/07 Des Moines Los Lobos show is still torrenting somewhere, give that a listen. One of the best recordings I've ever made - Healy, 5' LOC at the board, in a KILLER sounding outdoor natural amphitheater.
