Great job on tackling the scary looking DPNs. I recently did the same after numerous frustrating attempts at casting on spacey enough to get my knitting to fit around short short cables!
Now I put all my stitches on one long straight needle and then divide them up onto the DPNs. I know a lot of people don't like regular straight needles, but I find lots of uses for them. I also discovered that the bamboo DPNs make working in the round much easier because the bamboo keeps the stitches from slipping off so easily.
Your Coco looks like it's progressing nicely. Can't wait to see the FO.
