Black and White recent happenings thread!

Currently I'm working on a subway team consisting of Excadrill, Altaria, and a bulky water (don't like Jellicent so maybe a Regenerator Slowbro). However, I'm having trouble getting the correct natures and IVs when breeding. This leads to a question for you guys. When you guys are breeding, would you settle for a beneficial nature with decent IVs or a perfect IV with a hindering nature?

Beneficial nature with at least 1 perfect IV for me. But I try to get at least 27+ for important stats at a minimum. Hindering natures will always bite you in the butt one day during an important battle.

Also, Milotic is a very good bulky water as well if you'd consider it.
