I am torn on this bra.
The side of me that is sick of feeling my chest ache after running, and who gets embarrassed if I wear a non-supportive bra in the gym on the elliptical absolutely loves the minimal bounce when I wear this bra.  I think I notice all of about an inch of up and down movement, and the 'girls' feel very well encapsulated and constrained.  I don't notice the movement when I'm running, which is quite unusual. I don't think you'll find many sports bras that are as supportive and movement controlling.
The side of me that loves my lightweight high tech workout clothes hates the feeling that I am wearing a small blanket under my top.  I wish there was a way to have the same support with a bra that feels less like wearing an iron lung.  The neckline comes up very high, and actual shows at the bottom of the V-neck for some of my running shirts, which is awkward because then the zipper pokes out and it just looks bizarre.
I do like the zipper because it helps me ensure that the bra is super snug because I don't have to worry about yanking it over my head after a workout. (Anyone who has tugged and fought sweaty sports bras in a humid hot locker room will appreciate how this saves a good deal of your dignity.)
I have finally decided to relegate this bra exclusively to high impact activities (running, soccer, basketball), because the extra support is great but the blanket feeling is too much for activities where I can get away with less support and more breathability (yoga, weight training).
