First of all, if you tend to size down on the band, you might want to get a size bigger. I personally wear either a 32 DD or a 34  D in normal bra size. However, knowing that all previous sports bras I had before did not provide the support I needed, I sized down on the cup and chose the smaller band, so I bought two 32 D's in different colors. I had to return them and buy 34 D's instead because the back has a really non-stretchy spot that made it almost impossible to wear. For these reasons, I would recommend to get a comfortable size band rather than tight if you're used to tight. Apart from this, great support all around, and the adjustable straps is a plus for those who like to feel upright and not saggy.
