If you can save a few bucks from this..... The standard mounts are totally adequate. You can mount a mic upside down w/ no worries of it coming loose!! You could shake the shit out of the mount, and not effect the mics positioning in the mount, fwiw....
I taped a quiet show at a bar a couple days ago here in town w/ my TL's, hypers, in XY (using a vert bar) - someone knocked over the stand, and the post hit a table, and he caught it, and set it back up;
After I normalized the recording in SF6 (RMS, not sure the % off the top of my head), the recording sounded really, really good, and you can hear the stand moving, but suprisingly it did not make a huge, nasty sound on the recording...noticable, but not completely terrible. I am going to give credit to the shockmounts for that!
As for the recording in general, I think it is the best one I have made yet. I love these mics.
Question though- you can get 17.5 cms, but how does the dollar measure the angle? Using the corner as a right angle or something? I have often wondered how you guys know that the diaphrams were 120 degrees, etc. - is this a estimate, or a measurement?
