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!
