I'll make it easier for you, as there is a lot of pages to go through to find the options raving. (believe me, I read every page) But I have only been knitting since September 06, and switched from plastic to Options in December. I LOVE them.
The screw in cable join is wonderful, it doesn't slip out and does not get caught on the yarn. The cables take a bit to uncurl after being factory sealed, but after one or 2 projects they are so light and flexible it's wonderful.
I've never used Addis, but I HIGHLY recommend the options.
