Set-ups for the left hook

[Zelley]

So, I'm a lefty that fights orthodox. I got a big left hook as can be expected, and I have alot of success landing it. Naturally, everyone in the gym knows it and I have been having to get crafty and sneaky to land it. I got a bunch of ways that I set it up, but I'm looking for any advice that may help me.

Throw me whatever good set-ups you have and what subtle things you do to set it up. I'd also like some tips on how to make it quicker. And any good drills you may do to further develop it.

I've been doing alot of studying on good ol youtube. Watchin all the left hookers I can find. Who are the best guys to watch? I've been watching alot of Tommy Morrison clips, he definetly had a badass left hook, and I fight somewhat similar to him.

In the third Zale vs Graziano fight, Zale set the left hook up by throwing a right to the body, and after landing it, Zale unleashed a deadly left hook
to the chin.
