I am using a TC Harmony G XT for tone shaping and harmony fills and our current crop of mics are feeding back horribly when I am not standing directly in front of it.. With both a SM58 and Heil PR20 the TC causes feed back and chatter. I know...quit using the TC 
I know that the gate in the TC isn't the best, but I have read that the feedback rejection of the Rode is supposed to be pretty good.
We play on some pretty small stages and the stage volume carries the room. I have my amp and the bass player on my side of the drums.
We all have floor monitors.
The setup is not going to change much, so I need the best feedback proof mic I can afford.
