I need the BEST TH8 farming base design

here is the link for pingfao's tesla theme park
Pingfao's Tesla Theme Park [Revamped] - A TH8 Design

My one works amazingly try it out

Since i am farming now, i am using PingFao's [Farming] Version 2.0

Base is good, specially the Funnel is awesome.

Even when my all Wizard Towers and 1 Archer Tower were under upgrade.
I was attacked by 9 Drags lvl 2+Heroes+Rage Spells+Archers+Castle_troops only 70 % damage.

I use one of Childish's old designs, which I modified to my specific needs:
