I like to go the other way with pairings.... single gene females (cheaper) and multi gene males. It is not the best of plans to breed your females down genetically and a 1.0 Pastel is about as far down genetically as we can go.

For females (bred with your 1.0 Pastel):
Firefly- (Super Pastel, SuperFly)
LemonBlast- (Super Pastel, KillerBlast)
BumbleBee- (Super Pastel, KillerBee)
Spinner- (LemonBlast, BumbleBee)
Black Pastel- (Black Pewter)
Enchi- (Enchi Pastel)

You should be able to get any two.... maybe three of these 2013 females within your budget.

I would get a Firefly, LemonBlast and a Black Pastel and start thinking about another male- Enchi Fire, Enchi Pastel, Enchi Butter.
