Lol. I didn't know Addi Turbos were all that special. The Turbos and Naturas are all my one and only LYS carry. They are the only things I've ever knitted on. Cool. Shows how much I know.
I have about 7 different sizes and I definatley prefer the Turbos over the Naturas. The join is SO much smoother on the Turbos.
I also have never had one coil. Ever.
