I am quite a bit smaller at a fluctuating 34D/36D (gosh I never get to say I small up top ). I like the Moving Comfort bra for running, for cycling I can get away with less support unless I am mountain biking. I was hesistant about the price of the moving comfort so I finally found one on sale at REI to try, it is worth the full sticker price. I think mine is the Fiona but I would have to look at the tag.
