Focus Punch (Warning: Contains Copious Amounts of Pokemon)

I've been thinking about something. What is the best way to go about using Focus Punch?

My top three:
Hitmonlee (Hasty Nature) Sub-Punch
Breloom ______"_____ Spore-Sub-Punch
Dragonite _____"_____ TWave-Sub-Punch
Opinions?

I run a choice banded Typhlosion with focus punch. Because eruption does huge damage regardless of resistance or not, I can scare people into bringing in their special walls to soak to hit only to be punched in the face. But yeah, Breloom is one of its best users, safely setting it up. Pretty much most bulky substitute users can use it well.
