Thanks for the video links especially the Channed Island cast on from Eunny. The picot bind offs that I've seen aren't quite as subtle as this cast on so you may need to play around with them if you decide to use one to balance the CICO. Really, a provisional cast on is ideal for perfectly matching edges. That way you could do the picot bind off on both edges.
I'm intrigued to see this bracelet. Do post a photo in progress or when you finish.
