I knit continental and I watched Amy's video to make sure I was doing it "right" cause I used to knit combination style and changed over the last couple of years.
I don't use my fingers at all to push the yarn down. I just scoop it with my needle and it seems to work fine for me. So what ever is comfortable for you as long as you are wrapping the yarn in the right direction and not twisting your stitch.

Well, I've wrestled with reality for 35 years, Doctor, and I'm happy to state I finally won out over it.
