This constant arguing over what causes crankwalk is dumb.
I dont have any idea what actualy causes it.
But I do believe that the nitrating of the 2g cranks helps fend it off just like the factory nitrated 6bolt crank tends to fend off crankwalk.
I am not sure how anyone could say that the nitrating of the crank plays no part in crankwalk. There may very well be more to it but it definitely plays a part.
Deductive reasoning tells you it has to.

I am still partial to 6bolt motors though.
When I get my EVO one day that may change though.
