Yes, this discussion probably belongs there, but IIRC almost all of it concerns bras for large-breasted women. As those motion studies have pointed out, small- and medium-breasted women have just as much trouble with bounce.

I'm a 34B also, and my choice of the moment is the Champion Double-Dry Glisten. You just missed a big sale over there Very firm support for running and high-impact aerobics, without a band that's so tight it keeps me from breathing; room for a HRM; no chafing when wet.

I haven't found a bra yet that's supportive but doesn't retain sweat; but these are still comfortable and supportive even when wet.
