I only use straight needles for large projects like blankets, throws, etc. I use Circular and DPNs for everything else.
However, and I only mention this because I just got a new set of needles in (Quicksilvers) be very sure that the joins between the cable and needles is smooth. The #3's I just got catch the yarn and it's setting my teeth on edge. Two more rows and I can change needles.
Knitting to keep my sanity. It's working... kinda...
