Ahhh the age old question for running gals. Sadly, there is no easy answer cause no two "girls" are the same
I use Aftersock (from the Bay in Canada) and even though I get well packed in, there is no bounce and can still breathe. Think it was maybe $60 and worth every cent.
All I can suggest it try and find one that is adjustable a bit (mine does at the sides) so you can tweak if you need it during a run.
Best of luck. The only thing worse than bra shopping is SPORT bra shopping.
