In your case(hardrock) I´d go for the low-sens-modded SP-CMC-8(AT943).
Some here say the AT943s don´t benefit from the low-sens-mod, others say they had distortion with the standard AT943s....
Cards are the better "all for one" mic ...indoor shows with chatty crowds and bad acoustics =>that´s where cards should be chosen.
A good taper NEVER turns his head or moves during the show
, you need a good (and pretty) masseuse after the show so be prepared
!
You also need a battery box...12V(50 hours) are smallest...9V are slightly larger and longer lasting(300 hours).
For in front of stack taping with earplugs you could use omnis too ....more low frequencies.
THE GOOD thing using sp-cmc-8 are the iNTERCHANGEABLE capsules!
You can always get omni caps later for 120$ NEW or used here in the yard sale and use them on the same mic-bodies.
Low-sens-modded AT853(SP-CMC-4U) perform very well too at high SPL but are bigger than AT943s.
another option: Church cardioid mics from Chris Church here who sells his mics with interchangeable capsules now aswell.
