These two you can pretty much combine as they are almost identical, in fact you can pair them to each other to get the super form aka BEL.
I definitely keep a list too as going to the reptile shows can be overwhelming (kid in a candy store) and I may forget what I'm on the hunt for next.
Here is my current list:
0.1 Leopard
0.1 Clown (reduced pattern)
0.1 Blade
