Caught a Frillish, with the intention of having a Jellicent as a special wall/statuser on my team. Took several that I caught to the IV checker, and most of them were not very good. One, however, was outstanding. After giving it some rare candies and running the stats through an IV checker, the results are pretty damn good.
Perfect IV's in HP, SpD and Speed. Defence is 29, and the attack is 28. Only downside is that SpA is 7. What I wouldn't give to have the two attack IV's swapped. Can't be helped, and I don't think I'm going to get better than that without breeding, which I can't be bothered with. For what I'm going to use it for, it's perfect.
