I have the organic in whatever that neutral type colour is called... beige or fawn or whatever. I also have the heart to heart insert, and it's great - means I have been able to use it from birth, although I didn't use it til she was about 5 weeks old. The insert is really good as it just provides that little bit of extra head support for her, which is especially great when she's awake.

The sport does sound good, for the cool factor, but I find this one (wearing it right now) plenty cool enough, and I live in steamy Brissie.
