So, I begin this topic with my 8 to 8 balancer:

Sure it could be sized down, but who cares? It looks AWESOME!
The design is based off of a symmetrical 4 to 4 balancer, then scaled up by replacing each 2 to 2 (normal) balancer with a 4 to 4 one.
Unfortunately I lost the blueprint for it, but I will post one soon.
