Does anyone have a good aiming layout?

Hey guys. So here I am absolutely frustrated at how complex they made aiming. After sitting here for a good 45 minutes to an hour, I can’t find a consistent aiming feel to make the game enjoyable. Did anyone figure out how to make the game feel like Halo 3 or even Reach?
I never had this problem in any of the older Halos where aiming is so frustrating. Just Halo 5 and now infinite.
If anyone has a good layout to make aiming feel smooth and consistent, please share it. I want to give this game a chance and as it stands it’s not looking good.
