I am also looking at getting an ergo but am tossing up between the normal and the performance. Has anyone used/heard anything about the performance?

Thanks
I have the performance, it is very comfy and apparently 1/3 lighter than the normal one, and not as chunky looking. It is much comfier to wear on my back than on the front. I have used it on long walks as well as around the house for long periods of time, and love how the weight is distributed. I also a sleepywrap, a mei tai and an African sling. My favourite by far is the sleepywrap which I have used since my bub was a few weeks old, and absolutely LOVE it. Have to say the Ergo is not as comfy as the sleepywrap, but it is great for back wearing.
