Pastel Fire, Pastel Vanilla, or Pastel Ghost

[AmA]

Hi... This is my first post here. I hope someone can help me answering my question.

I like bright clean yellow color. Which one should I choose to cross breed Pastel with? Fire, Vanilla, or Ghost?

I have seen photo of adult Pastel Fire, Pastel Ghost, and Pastel Vanilla. They all look similar to me, but I haven't seen them in person so I don't know which one is the best looking.

Also, what about Super Pastel Fire, Super Pastel Ghost, Super Pastel Vanilla, or Super Pastel Super Vanilla (don't know if there are any?)? Which one will look best when it grown up?

I learn that Pastel Vanilla is the more expensive than Pastel Fire and Pastel Ghost is the cheapest of the three. This mean Pastel Vanilla is the prettiest one?

Is there other morph that when cross with Pastel, babies will have bright clean yellow colour when they grow up?

Any advice would be really appreciated.
