Kangaroo Sling What Is Your Favorite "baby-wearing" Sling?

What is your favorite "baby-wearing" sling? - kangaroo sling

I'm trying to get a new one, my son is nearly 1 I had three different slings / carriers, which some of them eliminated, others were hard on his back. There was a deep front loader when he was a baby, and then moved to the style of the backpack (like Bjorn), but now I might see a Moby, Peanut Shell, K'Tan, kangaroo carrier, etc.. .

I am a bit of money for tired, not working or damaged.

Tips, tricks, especially for older babies? What company do you prefer?
