Baking a cinnamon-mango, sweet potato pie...what type of crust should I use?

Standard pastry crust would be fine. Not sure I would go as far as "should," but some other ideas are:
A) to play off the mango tropical notes
* macadamia nut crust, like this one from Alton Brown:

* standard graham cracker crust with with a bit of dried coconut in it and fresh shaved coconut to garnish the finished pie
B) to play off the sweet potato & the cinnamon:
* a chocolate cookie crust, like this one from Serious Eats
