Go traditional and chop back to the first branch
Go daring, keep everything and make it a windswept
Go boring and just reduce the branch to halfwey to the trunk
There are enough traditional or boring trees around. If you have space for an experiment, I would be tempted to go daring. Nice wiring of all the branches to get a uniform unidirectional canopy going. Extend the already chopped branch and make a shari along the bare side of the trunk. Then let it grow for a year years, every year wiring the vericals back into the rythm.
