Congrats! That's awesome, especially if she's not a hatchling and is only a year away from breeding size.
Spider pieds are nice but tend to only have color/pattern on their heads and pure white bodies, just something to think about. Difference between a Spider Pied, Bumble Bee Pied, or Killer Bee Pied you are mainly looking at difference in head color/pattern.
If you want a pattern morph involved with your project and don't want to make just white snakes with pretty faces, you might look into Pinstripe as an option. A Lemonblast het Pied male would give you the possibility of getting Pieds, Pastel Pieds, Pinstripe Pieds, or if you are lucky Lemonblast Pieds on your first breeding.
There are a lot of other really great Pied combos out there. You'll have alot of fun picking out your male and I think you'll really enjoy working with morph balls
