My opinion, based on what I have seen, is that they are just right for you. But then some guys (and I do not understand this myself) think that the bigger they are the better. Personally, I think the more proportionate they are the more attractive they are. I don't think a 100# girl looks good with a set of EEE's nor do i think a 150# woman looks right with A cups. I think they need to match the build.
There is one more thought on this, and it applys to lots of things. Opinions are like assholes, everbody has one and they all stink.
