Looking for some opinions on a Goodra set at the moment.

I currently have:

Goodra@Assault Vest
Modest
31/XX/31/31/31/31
Draco Meteor
Fire Blast
Sludge wave
4th move.

Not sure about the EV distribution for this one. It could be invested in Sp.Def, Def and HO to make it even bulkier or Hp and Sp Atk to make it bulky and boost it's Sp Atk a bit.

I've also been thinking of a second set:

Goodra@lLum Berry
Impish
252 Hp, 252 Sp.Def 6Hp
Curse
Rest
Outrage/Dragon Tail
another physical move

The second set is basically a bulky mixed wall. You curse to boost defence and attack then use rest when you get low on HP then proceed to fuck shit up. Acid Armour Could also be used instead of Curse and the physical moves could be replaced with special moves and Impish replaced with Bold

What do you think?

There are literally so many options for this guy and I'm fairly new to competitive battling so I have no idea what to use him for.

I'd appreciate some advice.
