Hey, I know that shiny hunting, SRing especially is time consuming and hard to stick with, but resorting to using AR every time you grow impatient, really doesn't answer it.
People on the club really frown at cheats, even ones that people admit to, so try and keep those statements to yourself, kay? Otherwise some people could look badly at you and assume that you do it to all of your shinies (saying that in the nicest way possible), when you obviously don't.
Instead of SRing Heatran, why not try and hunt for a shiny Pidgey on LG/FR if you have one of the two? Pidgey is monster-common at Route 1, and both Pidgey and Rattata give off Speed EVs if you're an EV trainer, so it's convenient to hunt there.
