I have not used the naturas. But I do like my wood and bamboo needles.
They are not very fast with some yarns though. Wood and bamboo are a bit grabby on yarn. But wood was my needle of choice before I bought my addi turbos.
I adore - love - would marry my addi turbos. :rofling:
The turbos are made of hollow brass. Brass is very forgiving on the hands and the needles are quite light. These are nothing at all like the solid cast aluminum needles. No comparison!
The best thing I like about the turbos is how incredibly smooth they are. Silky. I have arthrits and tend to knit (and purl) too tightly. But I have no hand fatigue and my stitches glide right off.
Also if you get the circs (my favs) the cord is very flexible and soft. Not at all like the hardish nylon on other needles. The hip (where the shaft tapers to the cord) is very smooth. No weird humps or ridges to catch on.
I am a novice knitter - I had thought before I bought my turbos that the ultra smoothness would be problematic and too fast for my less than dexterous fingers. But I have found my knitting to improve now that I am not fighting the needle. Oh yeah - I love my turbos
