[quote="dmtaylor":1r2todr8]I would lop the top 2/3 of the tree right off at 3 or 4 feet high, and then watch as that tree bushes out big time the next season.[/quote:1r2todr8]
Agreed. Lop off the ‘trunk’ at the point you want your highest lateral branch to form; the other branches will pop out below. You will loose those pretty top branches though, and that’s a shame cuz it’s a healthy looking tree.

And – prune while it’s dormant (and preferably dry), not now. You’ll want the energy it sends and stores in the root system to push up and out into the ‘latent’ buds that will form it’s branches next Spring. The branches will be ‘one year behind,’ but the tree will have ‘dug in’ and is poised to ‘bush out big-time’

Leave the trunk leaves; they collect energy and shade the bark. If one of those leaf bunches (or fruit spurs) were to ‘take off’ growing and begin competing with the limbs that will emerge after the heading, pinch it’s tip growth out (to slow it up) or snip it off at the trunk. But leave the little ones, they may even produce fruit
