I use my Knit Picks Options Sunstruck needles and they work fine for me. I have a CiaoGoo Red and don't think I'll use it for socks again, the ergonomic bend makes it harder to use and the steel cable isn't as flexible as others I have. I don't like my Addi Turbo, the cable is kinked and the tips are too blunt. I do ML 2 @ time socks, a 47" circ is about as short as I'd want to go.
You can't knit the left sock first. Ever.
