As far as 'USe of the Secret Ingredient' goes, I was more flexible about it than arguskos and Hand_of_Vecna. I'm of the opinion that a good build takes what it needs from a PrC and then gets out, so the 7/7 split builds didn't bother me as long as they actually used the MoM well.

I probably would have graded Keiji higher if he had left MoM 2 levels earlier and gotten 9th level spells from AoP, actually, since that makes more sense than stopping at 9, 1 away from the capstone.
