TH8 Attacking a TH9

Hey I just got robbed of about 1k DE last night. He is a TH9 decently leveled not the best but I have a mass drag raid ready. I was only holding about 18k in my stoarage at the time and he has about 36k so I am planning on taking it all back. I am a TH8 with level 3 drags and maxed rage spells. Should I use the mass drag strat. or should I go with something else. All four air defenses are kind of leaning to one side aslo and he is farming so I can snipe TH also to ensure a win. I used all the rest of my dark, I got a few more K from my CC from a war win bonus and started my level 5 BK also. So I am really low right now. Any tips or advice?

what level are his air defenses?

one is being upgraded to 7, he has one done at 7, and the other two are 6.
