I have been using the Black Hole, designed by Mavios of Ironbound clan and can't praise it highly enough.
I started using it at TH9 to help with the constant Hog attacks whilst saving for TH10.
Original thread for Black hole is here:

Apart from the standard anti-hog ring the key to this base is the doubling of the giant bombs.
Putting 2 giant bombs together like that and leading the hogs on to them totally smokes them. Level 5 Hogs can scrape though from level 3 bombs (max available at TH9) with a sliver of health but the wizard tower/xbows will finish them off. And it usually leads to the attacker throwing out a heal potion too late and wasting it.
After my TH10 upgrade finished I liked the design so much I kept it with a few tweaks. Most attacks now get in the region of only 1-30%.
It lends itself well to farming with minimal conversion – the TH gets moved out to a far corner, the CC goes central and the DE storage goes where the CC was in the core.
This is a take on Mavios's TH9 base for a TH10 trophy layout (using this now to push to Masters):

This is how it looks to the attacker:

If anyone has any pointers on how it could be further improved I'd like to hear them.
Thanks (and thanks to Mavios too).
