I have colour rings for Coscom and Arda and of the two, I would say the best colour is Coscom's Shadow Green
. People are wary of ordering from here because there have been shipping and communication issues, but with this one day shipping being promised those issues may be laid to rest finally.
If you do decide to go with them based on that colour, then I would suggest the Ivy Long and get some extensions to build the wingy bits. It may even be advantageous to buy a short clip, as you want a lot of fiber for them.
