This works much better with lv6 balloons due to the big increased in hp from 5 to 6. If you have lv6 balloons, most likely you be with 220 spaces with 4 spells.
With 220 spaces, you want to have around 28 balloons and 6 more in your CC. Have some barbs in helping to lure CC troops to corner and the rest will be minions. Play around with this numbers and dont be stingy with the balloons. You definitely need more if you are thinking of 3 stars.
With 4 spells, you will like to have 3 rage and 1 heal. Never bring a lightning. Its a waste to use it to kill CC as with practice, you can do kill it easily with your own troops. Not to mentioned that lightning will be useless when a dragon come out of the CC instead.
But everything is also highly depend on the base design you going to tackle. Sometimes, 2 heal is needed or 2-3 hogs/giants are needed. Just follow the basics of lure CC, break chain, storm the core, minions to follow behind to utilised the rage, etc. With enough practice, anti-hog TH9 bases will be like a easy 3 stars target in clan wars.
Enjoy the balloon minions raid.:o
