Ballonion strategy?

hi, I wanted to do a trophy push an heard the ballonion strategy is the best for th9 so I wantend to know what number of troops to use becaise i've seen a lot of variations. Some use 32 ballons and others drop down to 20 balloons and 60 minions si I wanted to know the sweetspot.:D

I did a Master Push a few days ago. I got up to 2756 with 24 Balloons, and rest Minions. I will probably push again after this week, loot is wayyyyyyy too good right now.
