I don't like rope halters either. You'll likely see the fastest results from using any halter (nylon or rope) and starting slow and close. You have to give your house the chance to learn what you want him to know. Of course you're going to get puking and the larger the circle, the more pulling the will be. Go back to basics, be patient, and only progress when your horse is ready.
There are no short cuts. There are no quick fixes. Constant jerking won't do you or your horse any good.
The wind of heaven is that which blows between a horse's ears. ~Arabian Proverb
