Nodes: if you dont use any cheaty way to move them, make sure you drain the most from a node by regenerating fading nodes to pale (advanced node stabilizer), place them at the farthest point in the "bullying range" (3 empty blocks between them in a straight line) of the target node so it will drain the node slowly, giving the drained node time to regen itself and give more vis points to the target node.
Node draining is lossy for most people because they let the node get destroyed before it can regen. I managed to make a node get over 200 points of aer from a big aer node (120) and i yet had to destroy it mid-way (when it had like 80 pts) because i wanted to feed the node other aspects.
Another example is 48 permutatio as you can see in the node, from just a single node that had 14 (yes 14) permutatio aspect points.
Here is my prized bright node (third person cause too many aspects...):
