I did order the Harmony DPNs. They've shipped, can't wait for them to arrive.
I'm working on some new sock designs -- yeah, huge shock -- and I'm looking forward to some nice pointy needles. This new design is all cables and twisted stitches, and the points on my DPNs are just not holding up.
Not only are the bamboo points not very... well, pointy... but they're shredding a bit. They're getting rough. I don't have any complaints -- they've stood up well to a lot of use, and they're certainly still great for ordinary knitting. But I'm looking forward to trying the new ones out for cables.
I'll keep you posted.
