I would not choose church-cards as they are low-sens modded and that´s the last thing you need for acoustic not amplified stuff
as more preamp-gain is needed for the loss of -12db caused by the 4.7k low-sens-mod.
Chris himself recommends his mics for loud amplified stuff..I think 96db and higher, only.
You need some high-sens low-noise mics:
If you can afford, go for "DPA 4060" omnis which are high-sens....318€ for 1 mic + the DPA power supply "6030" or have them 3.5mm modded so you can use them with a 9V battery-box.
I just emailed you a sample from yesterdays session:
MM-HLSC-1 on RH1 MIC-in at gain 13 with plugin-power only...no bbox or preamp was used.
