I rarely ever use more than 1 Mic, my favorite is the EV RE20 / PL20
with this Mic i have no problem getting a great kick sound,
If its not sounding good i will mess with the drum till its as good as i can get it, then i will EQ to tape then add more later if i need, I rarely have to add subs mostly 1k to 3k for the click and a bit of 60 HZ and 80 HZ Aproxmantly.......
I don't look at the numbers i just turn the knobs tii it sounds good .
