Looking for DE farming VOD's and helpTH7

Hello, I was just wondering if anyone knew where I could find videos of DE farming at TH7? I read a couple of guides and stuff, but I would really just like to watch some videos to see how raids should look. I got to TH7 pretty fast, only in a month or so and I feel like my base is not rushed by any means. I am just looking for a challenge and I believe DE farming at TH7 would be just that. Any more guides would be nice as well, I have only read one by strikeninja on the forums so far.

Also if anyone could help me with my base and what I should upgrade next that would be great.
Clan: The Stain Train (my friend knows a guy by the name of Stain)
Name: Vulb
Level: 46

Troops:
Lvl 3 bars (being upgraded)
Lvl 3 archers
Lvl 4 giants
Lvl 3 wall breakers
dragon
Lvl 3 Lightening spell

Basically , get your troops to lvl4. push to gold. take out full drills and supplement cups with snipes...

revenge zap.

not a lot to it really.

Costly, but you have excess elixir to burn at th7 anyway, and you get to improve your attacking skill.

10 lvl 2 dragons are good enough to 3 star any th8s without lvl 6 air defenses.

thanks for the replies, I'll have to try the dragon one while I sleep over night and then a less time consuming one while I play
