Yes very similar to a the yarn and egg fly imiations used for trout, steelhead, salmon. Since I don't use these much any more (except when I am desparate for a fish encounter) I can justify using the many in the fly books, yes for carp. Suckers also take these readily.
Thanks, and keep us posted on your continued research.
Don't give up on the hex nymph pattern either, its a go to general nymph imitation for many fresh water species.
