I used a ring sling and really loved it. With DS1 I found it took a while before it was "easy" but then once I got the hang of it, it was easy, so with DS2 I was right from the beginning. The trick is to follow the instructions carefully - and make sure that bub is on the seam. Then it works well and I found that I mostly could just pull it on and off, I didn't have to do it up from scratch very often.
