On the dynamics, I did use a Heil PR40 for my main pair on everything for the longest time. It was alright to good at everything below 8 to 11 khz. I probably should just get one for bass reinforcement. I imagine the RE320 is similar.
Still, I probably should test a PR40 or equivalent dynamic versus a regular omni condenser in this bass-support role.
I had a MKH 8040 pair out for fireworks one year and it was a no-go as a main pair. I think I was overloading the preamp in the capsule or the equivalent. In post I was not able to salvage anything, too sensitive. I would not be able to use this in the bass reinforcement role. The really nice SDC omnis are a bit expensive for my risk tolerance. I sometimes things get messy, wet and I sometimes have to leave the sound rig without being completely secure.
