What's a good Tanky Build/EV Spread for Crobat?

Question

Yes I know it's crobat not the BEST EVER TANK in the universe. But I do like it's speed and Typing since I don't know any other Poison/Flying from my top of my head, I don't know if there are any. Anyways because of his Typing he's able to Resist Fairies, Fighting, Bug, Grass, Poison and cannot be poisoned, and immune to Ground obviously =P.

Right know I cannot think of a good EV Spread for him. Should I Max Hp, and 126 EVs with both Def. and Sp. Def?

Or Take advantage of his Speed and Put EVs on Hp? or the Same thing but instead of Hp it's both the Defenses?

Or Evs on Just Defense and Hp?

So yea, would like someones input on this, would be much appreciated =P

Answer 1

Dude, you do know that Crobat is a glass cannon, right? It really wont be lasting long as a defensive bat. It doesn't have the defence nor the sp defence to pull it off. however, Golbat can:

Golbat @ Eviolite
Ability: Inner Focus
Nature: Impish/Careful
- Brave Bird
- Super Fang/Toxic
- Taunt
- Roost

That's as defensive as it can get.
Sp. defence was 75, with evolite its now a stunning 112.5 - higher than even Snorlax's! Defence was 7, with evolite its now a much better 105 - higher than Blastiose, Claydol and even Articuno!
