I haven't seen Friends of the Dragon!
Is it a replacement for Golden Comeback?
Somewhere, out there on the net, is a site that lists the original system they used for balancing the archetypes. Useful if you need to make your own.
I've found that it's useful to compare it to exalted.
After playing both I greatly prefer Feng Shui but now play it where the stunt gives you an increased difficulty, but also a nice bonus.
There was a nice crossover adventure to d20 that gave out some awesome suggestions for making your d20 game more Feng Shui.
I purchased Golden Comeback at a store recently, it's not impossible.
