This bamboo circular needle is definitely a better needle.
I ordered a 16", No. 6 Takumi Clover needle from Yarn Barn in Lawrence. Bamboo, which means the color will be a neutral ecru. The pale color will be a very helpful contrast to darker yarns. It's difficult to distinguish the stitches if the yarn and the needle are a close match.
The needle points are the sharpest I've ever seen in a non-metal needle, which really seems to speed up the whole process. Something unexpected was the swivel cord. The cord and the stiff needles connect very smoothly, and the cord swivels at that joint.
These may become my favorite needle.
