I have an M37, which is the exact same mic as the 177 but in a slightly different housing that used to be sold on Musician's Friend. I've never used it on rack toms but I really like it on floor toms. I don't use the high pass there, obviously.
I don't own a mic that sounds better on floor toms than my M37. It's actually kind of a drag because I don't dare use it if I'm recording any other instruments in the same room as the drums, as the bleed would be a nightmare. So I rarely have a chance to actually use it on floor tom.
