One nice thing about using Haggar on point is that when the shit hits the fan I can always throw out a Lariat and beat almost anything. I almost always hyper-cancel the Lariat into Rapid Fire Fist for decent damage. It's one of the few supers in the game where mashing buttons gets you extra hits, but I only learned this morning that it actually has 3 levels.
Level 1: Don't mash (12 hits)
Level 2: Mash a bit at startup, eyes glow white (18 hits if they all connect). I mash ABC so I don't accidentally use X-Factor.
Level 3: Mash a lot at startup, red glowing effect (30 hits). So far I've only pulled this off in practice mode with a turbo controller.
Normally I do Lariat, cancel into the level 2 version of Rapid Fire Fist, and if all the hits connect I follow up with an air pipe for one more hit. I just tried a few variations on this super and different followups in the lab:
lariat super1 hoodlum MM headbutt swing: 455,000
lariat super1 airpipe: 363,400
lariat super2: 379,800
lariat super2 airpipe: 397,800
lariat super2 icestorm: 561,900
Edit: I guess it's more damaging not to mash this super so I can follow up with an air combo, but you've got to catch them on the way down with your launcher and it's pretty easy to miss. Mashing to level 2 is guaranteed damage.
