Hi, I saw what you said about measurments, but I don't have specific ones. My mom always said that deviled eggs come out better when you're adding things "to taste". Anyways, you obviously know (since you've made deviled eggs before) how to hard boil, peel, split and fill the eggs, so I'll just tell you what I put in with the yolks. Again, this is to taste so you'll just have to play around with it a little bit. Try making 5 HB Eggs and fixing up each yolk differently until you find a combo you like.
Mayo (must be real mayo, no fat free and no miracle whip)
Yellow or Dijon mustard (depends on preferences)
Dill pickle juice (gives a nice little vinegary kick, but not too much, add a little at a time and watch the consistency as you go)
Salt
Pepper
Horseradish or minced garlic (just a little and only if you choose, the purpose of these is to lightly flavor, not kick people in the rear! :)
diced onions (these are actually important, onions contain a substance that actually sensitizes tastebuds and makes the other flavors come alive, you can dice and crush this up so they are very small and difficult to feel, and the substance will still be doing it's work)
Garnish with paprika when egg halves are filled
I use these ingredients regularly and always get rave reviews on my deviled eggs. Actually my 6yo son told me that they're so good, they should be called angeled eggs. :)

Sorry to edit my response right after I sent it, but I forgot to tell you that I use a garlic press to finely mince my onions so they're almost undetectable except as a flavor.
