Sure, I'll try to make a Town Hall 7 version.

I've also added in another picture to show triangular defenses and pentatonic defenses.
Here is a quickly made TH7 Version:

Bases like this are my favorite to raid. BAG with wallbreakers and rage would easily be able to break the vault and steal the resources. The "ring" bases usually don't work for farming.
If u are going to do any type of vault at th8 you cannot have defenses inside with the loot. Your only chance is to have giants do a circle around the outside of the vault and funneled into a spot with giant bombs. Lvl 6 giants will tear right through this base.
I like the base, but don't you think the walls will be broken quicker? I wont watch all my first wave troops go around and destroy the outer core before sending in another pair of wbs to break the walls, that's what confuses me. Good funnel paths though.
The funneling and compact buildings make the wbs die because they cross paths with troops getting crushed by mortars. But someone with skill could break into this base (like any other).
Edit: I got 3 defenses now, I'll post my first log and a description of those defenses.
Seems like a good base to use, I might use it in the future when there are some logs and it's out of the beta stage.
