I learned how to skid stop using a 42/17 ratio, and it's no easier than doing it with a 48/16 ( what i ride now. ) The best advice I've ever given the kids I know who I've taught is just to let go of the fear pull that stem into your gooch, lift up on your weak leg, and push with your dominant. Which is pretty much what you just said, so I'm parroting you :3 sorry

Also, try it on slick surfaces like wet pavement, and to be perfectly honest, GRASS
Once you get the feel / general idea of what a skid stop feels like, you'll pretty much be set.
