Shunyata Python Helix PCs

I am looking for a pair of used or demo Helix Vx and alpha PCs and wondering how do they differ in appearance from the older non-Helix Python cords. I know the Helix cords have green ends, but I am not sure if that is different than the older cords. Thanks for your help.
I could be wrong but I think my Anaconda Helix has "helix" written on it.
The Python Helix connections use a green shrink wrap instead of red on the previous version. It also has Python Helix Alpha written on it.
