ChiaoGoo Red Lace Circular Knitting Needles 40"
I tried them on a cotton blend sock yarn and the needles and the cords were too sticky. Nothing would slide. Then I tried a wool blend sock yarn and there was a big difference. Nice and slippery. The cords are very flexible, which makes them great for two at a time magic loop. The tips are sharper than Addi turbo sock rockets, so great for lace. I prefer the coating on the Addi turbo sock rockets over the stainless steel ChiaoGoo's. The joins are smoother on the ChiaoGoo's. The labeling is so indistinct I don't know how anyone could read it. So I'll give them 4 out of 5 stars.
I love these needles. The tips are sharp, The joins are smooth and the cable is weighty enough that they (and any knitting in them) aren’t flying around as you knit.
