Allright, so I'm pretty new to breeding as far as these things go

After hours and hours, I finally got myself an adamant fletchling with gale wing and perfect IVs.

I have several alllmost perfect adamant gale wing ones too if anyone wants to trade, but that's beside the point.

Before I set into training my bravest bird, I wanted to ask the opinion of folks like yourselves who are better versed in this than I am; do you think I should forgo speed EVs in favor of HP or something since I'll always be hitting first with Brave Bird? Or are my defenses frail enough that it doesn't matter and I'll still want the speed boost for Flare Blitz?

I'm paralyzed with indecision, don't want to pitch a thousand soccer balls in the wrong place.
