I'm with Mysticaldream: save your gold until Humania is released. Going by the past couple of releases, there will be a short window around Humania's release where the prices of Fang sets will take a sizable dip. If you time it right, you can pick up crafted Fang sets cheapter than if you buy them now.

Going by history again, crafted Fang sets should be good enough to hit 70/71. Hopefully by then you'll have gotten enough pinks/gold for you to switch to Humania sets.
