I can't imagine wearing a regular bra for something where I get sweaty. I don't need the support, but I also have the armor piercing nipple issue and since I don't go bra-less in regular clothes, I don't do while riding. I need wicking!
I bought two Ibex bras this winter for x country skiing, but they still itched me a bit. I can take it for the winter, when getting hypothermia because my bra is not wicking enough is an issue, but for now, my vote to goes the Handful bra. It is so comfortable, has removable pads and doesn't dig into my ribs. I need to buy more. The 2 I bought last year are just about worn out. I have lots of other sports bras, but none are as nice.
