Whats a good Poliwrath Moveset?

[eeVee.]

I have an Impish Poliwhirl with me, and I was thinking of evolving it into a Poliwrath, except I'm not sure what a good moveset for it would be.

Poliwrath @ Leftovers
Nature: Impish (+Def, -Sp Atk)
EVS: ???
Trait: Water Absorb
MS:
~Bulk up/Hypnosis
~Brick Break/Wake-Up Slap
~Earthquake??
~??? Mind Reader, maybe?

I liked the Wake-Up Slap and Hypnosis combo, and then how Mind Reader makes Hypnosis always hit, but I heard that Brick Break is better.. so I'm hesitating a bit on what I should make Poliwrath know.

Could anyone help on the moveset and where I should put its EVs in?

- Hypnosis
- Waterfall
- Rock Slide/Poison Jab/Bulk Up
- Brick Break

A good EV set would be.
