What to what

[M&H]

Male lesser
Male spider
Male pastel
Female lesser
Female pastel

Im looking at going lesser x lesser, spider x pastel.

New females to pick up I would suggest

mojave (BEL, Mojave Spiders, Bumble Bee)
pinstripe (Spinners, KingPin, Lemon Blast)
Enchi (Enchi Pastel, Stinger Bee, Enchi Lesser)
Fire (Fire Lesser, Fire Spider, Firefly)

This is what I would suggest would be the most bang for your buck in my opinion. Anything with Enchi and Fire is super hot right now. With getting a mojave you can get the BEL as well as a few other neat morphs with other pairings (since you were thinking of the lesser x lesser). The pinstripe is to me something that is always a great pattern changer that everyone loves without the concern of nero problems like they have with the spider.

Good luck!
