Yeah, I did have to use my AR to check the IVs so I know which delay and frame I hit, but that's it. On an emu you can actually see the frame advancing and you know which frame you're on, so it's much easier to hit your frame.
I would just pick a Pokemon that you want shiny and then abuse for the nature and IVs that it benefits the most from. For example, a while ago I really wanted a shiny HP Fire Latias in a Love Ball. So I abused for Timid HP Fire and I just caught any other Pokemon I could think of that could use that spread :) Another example would be the current spread. I only picked it to get Piplup, but now I can use it for a bunch of other things!
