First shed should make a pretty big difference in seeing what's going on. After first shed if you want to attempt to get some regular and blacklight pics I can try to help more. Try to make sure you get a good side shot of the heads to help identify Enchi.

Mostly what you are looking for with the black light is pattern because sometimes you can see the extremely subtle difference between shades a little easier with that. You can also horse around with photo editing to try and get a clearer idea of what is going on, same as black light, certain settings can help make subtle differences more obvious, especially saturation and contrast.

From very, very subtle things, I feel like I am seeing:

Top- Enchi Spider Super Pastel BEL (not sure if Mystic or Special)
Middle- Pastel Spider BEL (not sure if Mystic or Special)
Bottom- Enchi Lesser Special Super Pastel
Right- can't see this one nearly as well because of shadow and the head being hidden but should be one copy of Pastel rather than Super Pastel
