After literally 40 minutes on clash builder I finally came up with another design idea that may be better than the other one we currently have? It currently funnels all around the base, has all collectors on inside and springs and bombs place in spots available.
It took such a long time for this design to be finished as I forgot about the space needed to spawn troops which means I had certain spots in the base where troops could be placed, this is my final design for this bit:

I did use nathans core.
