Look for targets with under-developed wiz towers. Two wars ago, I easily three starred a premmie TH10 using loons b/c his wiz twrs were all lvl 4 and he didn't have an inferno.
I have never not three starred any TH8 using lvl 6 balloons.
You must lure the castle and kill any troops capeable of damaging air units.
You must kill the AQ.
You must make sure your loons have set off all the air bombs before dropping your minions, but don't wait too long to put them down or you will run out of time against a large base.
Other people like rage spells, but I typically heal when they are approaching each wiz tower.
