Should you buy Addie? That depends on what you like about your bamboo. For instance, if you like that your stitches cling to bamboo, then you probably won't like Addi.
I like Addis b/c the stitches glide over the needles; Addis are quite slippery. I also like them b/c they are light and don't make a lot of noise when I knit. In the larger sizes of circs, the cord is just as thick as the actual neede, so you don't have to fight the stitches when moving them from cord to needle. See a pic of it here.I don't like the prices of Addis though :shock:. I actually only have two pair, but I adore both of them.
