I just wanted to make sure for the 2016+ that when doing a shim or sheave mod, the EPI purple spring is the one to use, aka it is still slightly stronger than stock.

Yes it is. The purple spring is the more commun general purpose upgrade. For those running 26 to 27" tires.

Those running 28 to 32" aggressive to extreme mud tires run gold or white.
