I'm a coincident fan myself when running on stage or at the lip.
In fact, the more FOB I am (right up to the stage), the more likely I am to run some form of coincident method.
on stage XY between 90 -120deg is awesome.
If the mix is "just exactly perfect" on stage, then blumlien is the way to go (or if taping un-amplified instruments / musicians). and, if you are considering XY ,then MS is also sweet as you get to play with various XY angles upon mixing.)
If you have LD mics that are good...I'd use those on stage.
the closer you are to the sound source, the better LD sounds.
as you move back into the crowd in any given venue, the SD mics tend to shine as they respond faster to the weaker pressure in the air (my thoughts have always been that taping from a distance w/LD mics sounds sluggish to me when compared to an equal rig w/SD mics from the same location. many 480 vs 414 comps in the past brought me to this conclusion).
but, thats just my thought process and opinion.
Its hard to make a stage tape that would be truly "bad".
experiment. two sets...two different configs.
