RE: Your Shiny Hunts?
Just finished Masdua'ing a Shiny Vulpix in X and Y, made so much easier by a Japanese 6IV Ditto. The good news is that she has the ability Drought, the bad news is that her one imperfect IV is in Sp. Atk (although based on calculations its still really high in that stat, like 26 or something).
I've only ever deliberately hunted one other shiny in my game experience, and that was my shiny Ralts, now Gardevoir, simply because I liked the look of its Shiny Mega Evo. I had a Japanese Kirlia for that one, which accelerated the process. I was done in a single day.
