All of the Parents I use are flawless, well most of them. I keep my Parents in my Platinum, then I trade them over to Pearl when I need them. I use my Foreign German Dittos, which have Flawless IV's (Only the ones with the Impish, Adamant, Jolly, Timid & Modest natures). It took me a while to get all of my Parents & Dittos, since they were a Pain to find. -.-
