I could go for Impish, as well, to help with bulk. Plus, if it's on a Sunny Day team specifically, Chloraphyl will let it outspeed most threats at first anyways, and let you get a couple of DD's under your belt before the sun goes away. Impish might actually be better for you if it is for a Sunny Day team.
Your call though. I'm doing the BP for you. Let me know the target IV spread, and Nature you want.
