i got 3 flips pretty much every try and want to take them to 6-10 sets any advice on how to flick/scoop/pop? t

The concept is still pretty much the same as doing them on flat.
Only difference is that you don't want to scoop it as fast, if that makes sense.
Like, you want it to spin slower, so there's not much of a chance for over rotation.

Make sure you can catch them good.
