first i have purchased just one color. it worked great as the belly of some bendback patterns. now i have 8 diferent colors. i´d suggest dark colors as black, peacock, brown, etc. for tying nice woolies´s bodies.
they really worked great for tilapias - so, they will work nicely for other small species such as bluegills/crapies, etc...
besides, it´s from hareline!
