Town hall 7 raiding/trophy strategy

I am just upgrading to th 7 and want to know the best army composition for raiding and trophy farming. Can anyone help me out?

For earlier stages when you dont reach to BK lvl5 use BARCH with 2-3 WB
When you could unlock BK and could reah hero to lvl5 you can use your DE for minions. so I recommend BAM.

Use your DE only for BK until lvl5 (the max level for TH7) then you can use DE for troops.
