The difference between the WC ones and the CB ones that I have noticed first hand is the head shape and secondly the patterns. The head shape of the CB ones starts off very rounded almost like a senegal then once ita around the 8-10" mark is starts to flatten out a little bit but still very rounded compared to their WC counterpart. Almost all the smaller teugelsi or even teugelsis that are being sold right now for around $40-$100 are CB. Price to me usually isn't a very good indicator as to weather its CB or WC, but one of the things I notice is that with almost all the people that are selling "WC" for $40-$80 have CB. There's only a select few people I trust to have true WC teugelsi. As far as pattern both CB teugelsi I have, have a base color (usually red if on black sand or light red/dark Orange if on garnet) and then with black all the way down their body. Where as my WC teug had not nearly as much black. It's hard to explain exactly unless you see them side by side. I'll try and find some pics to compare for a better reference to what I am talking about.
