Ah, made a mistake in my original post! I meant to write Mk41 heads on the tree.
I'm guessing you would expect an mk2 or variant for this application.
However, we once used this exact arrangement when we recorded a piano concerto and the hyper cardioid polar pattern really helped to get the correct balance between solo piano at.stage front and (what was being drowned out) the string section behind it.
Absolutely loved the sound it gave and so we kind of stuck with it.
However, the tree on its own is not perfect but I find this gels better with our omni flanks and gives up plenty of scope to adjust mid/side balancing with trees L/R pair relative to C channel.
If you have ever slung mics from the roof there pre referb then it's.much safer up there now and easier to hang mics accurately. However, now they have movable acoustic sails which get moved a lot and it always knocks your cables so you have to keep an eye on it closely.
