I have tried some slippery circular needles (by Addi and KnitPro) and I noticed I still prefer DP needles. Still I would want the same slipperiness as these premium needles had.
I have a slight fear of developing nickel allergy (after getting some rashes from my wedding ring), so I am looking for needles not having a nickel coating. If it would not be for this fear, I am sure the Nova Metal of KnitPro would be good. What is the most slippery DP needles made without nickel coating?
I tried the dpn from Knit Picks and liked them so much I ordered the entire set. Yarn slides easily over them. Would not go back to metal ones.
