Thinking about Babywearing?

I'm planning on babywearing upon our return. Mostly for the attachment perks it offers, but also because life sometimes requires you to have your hands free. I found this link the other day that sums up all the options nicely, but if you google "babywearing" you'll find tons of other articles and sites. (this one is a fave of mine) A friend is giving me a Bjorn, and I'm in process of making a mei tai... I'm still torn on wether a sling will make the final cut or not. What are your thoughts readers? Experience? Advice?
