This question isn't really that related to Pokémon X&Y but I didn't find any other place to put it.
I have a weavile and an ambipom EV trained and ready for competitive play, but they only have 31 IVs on Atk and Speed. I didn't really pay attetion on defenses and HP because I consider them really fragile and people tend to 1HKO them with the frustratingly popular fighting type. Should I continue to breed them until the have 31 IVs in everything except Sp.Atk?
Last gen I would have said not to bother, because the underlying systems all around were more obtuse than I was prepared to deal with. However, Gen VI has made it
frighteningly easy to select for good IVs thanks to the mechanics of the Friend Safari, especially for Ambipom. You should be able to find a decent breeding partner for Weavile too in someone's Safari; it's Field Group and you'll be lucky if you check more than one or two Safaris before finding something that'll hook up with a Weavile.
Hop on the #safari channel and dig around for someone with an Aipom safari, or check the google list. Catch a few, and with Destiny Knot breeding you should be able to produce a penta flawless Aipom with a desired nature within a couple hours.
I am a lazy sumbitch and if I can do it anyone can do it. Also... to be bluntly honest, there's a big thrill from running a freshly-hatched Pokemon through the IV Judge and finding a penta flawless. Got it with a Hawlucha just the other night and I'm just a tiny bit hooked now.
