I prefer using DPNs over magic loop. Also, I have nickel plated KPs but the tips are too sharp for me (and I find the needles too slick for non-lace knitting. ) I also have the plastic ones and they're ok.
I am considering getting Denise needles and I already have. several interchangeable sets. I love the fact Denise are made in the USA.
