I think it depends on your plans. Pastel lesser got my vote since you can super the pastel and take whatever you pair to her to the next level.
Kingpin female is cool because it already has a great pattern changer and will immediately be awesome when paired with spider.
I's a tough one. If you can swing it, having all 3 genes in 1 female may be expensive right now, but will be priceless once you get some weight on her. Go big or go home!
