I have two of these lovely Blue Moon Wisteria growing up separate posts on this large pergola. (The pictures provided are in the fall after leaf drop so that you can see the structure of the plant)

When I planted them I was too afraid to prune until they were established but now 3 years later they seem a bit unruly.

Question is should I try to find the stronger leader and cut everything else back down to the stump? Or will that damage the plant? I would likely have to unwind everything in order to figure it out.

Or is it fine as is?

Any help would be appreciated!
