You are right, it is more neutral and that's what the creater had in mind. And too, I agree with you, if you want corn just add some.

I wonder if adding maybe three or four boxes of the corn cereal might jazz it up a bit on the flavor??

Ya know I bet if you boiled a couple cans of kernal corn in a couple of gallons of water, then used that water in the fermenter it might add some cornyness to the wash and maybe some neutreints too but of course it comes down to the stillin method for the capture of that.
