I use both a 212 and 410 depending on the situation. I find that though the 212 has a bit of warmer tone to it, the 410 holds its clarity at higher volumes. Either way, you can't lose!
EDIT: Berg's sound great regardless of what size they are, everyone knows this!
410's do hold more clarity over the 212 unless the 212 is of equal stature wattage wise and frequency range imho
... it's going to be a good 3 weeks or so before I can get to a place to start testing...
