You could go for the old prop on the fence side.
The straight vertical leader looks good. Those other 2 large ones going over the fence look bad with little opportunity to target cut.
I would consider reducing them to something, even a small shoot/branch, then if it resprouts like one of those pics knock off all but maybe 2 good ones and then keep them reduced to. They'll feed to branch.
Too big a wound to take them off back to the trunk, and no need for a rot there.
Also, here's a prop idea from another thread/forum where
"experts" would rather install a substandard prop and cut the tree for ever till it's a knee high topiary.
In this pic the red lins is about where I'd be trying to reduce to those leaders ... look for something to cut back to around there. The yellow is maybe a prop zone but the fence is an issue unless of course the fence is modified to become part of the prop.
Mario, one last thing, thinning has be proven to take a lot longer for the tree to replace the floliage density ... thin the top out to reduce wind force. Maybe 20%.
