Well I used a Ditto with IV's of 30, 3, 30, 31, 31 and 31. I have all the second parents IV's listed at 2 (Since I don't know its exact IV's).
You really should figure out the 2nd Pokemon's IVs. Just collect your egg take your parents out verify the IVs and turn your game off WITHOUT SAVING.
Then you'll know exactly what will be inherited and if it will produce a desired Hidden Power.
