Echo the above sentiments, lotsa nodes on stabilisers for wand recharging and a super node for the centi-vis.
Be warned, bullying is really really slow with the 7x7x7 method. You can also just put a crap ton of nodes close by each other and hope for the best(great method if you have a teleposer and don't mind "cheating").
One more thing when energising a node a primal aspect is square rooted and rounded down to get it's centi-vis value, compound aspects give 100% of their primals. If you have primals and compounds, whatever will give the highest centi-vis is chosen.
For a super node this gives you 2 options:
1. 7x7x7 with big primal nodes and leave it a long time(intended use with "node in a jar")
2. Tons of compound nodes all piled around each other and see what happens("cheating" system with teleposers)
nodes on stabilizers take longer to recharge. If you space them out properly you can get SIXTY FOUR nodes in range of a recharge pedestal. So you really don't need to mess about with stabilizers or wasting nodes growing bigger nodes if charging your wands and staves is what you are after.
node bullying using the 7x7x7 method should be no slower than any other method. Especially as there is no danger that the contributing nodes can be fully drained. ... Allthough if node bully events are more frequent for closer nodes there could be some merit. But then you'd be wasting so much node capacity as they all bullied each other...
If you want a proper super node, nothing beats building a protective shell around a hungry node and building infrastructure to feed it crafting tables.
