My (needles) Point of view
Well I can honestly say these KnitPro Karbonz are extremely light and comfy to knit with. I love them! I recommend these if you want something light, smooth and comfortable and not cold (like the metal needles). These are worth the extra. I bought two pairs of these in different sizes and I also purchased a double point set, which I have not used just yet but know they will be just as brilliant.
