Hi Jim,
I like your idea with on the virt. Looking at your trees and at your virt I feel though that the trunks of your trees are still too long. If you look at the final height of your virt. you are a fair bit shorther than what you have now and ideally your trees should have more taper in the trunks. So I would be tempted to further shorten the trunks so they are a fair bit shorter than on the virt. Get some taper by developing new leads for the trunk and then build up your branches and your canopy etc.
Just a suggestion ( and make sure your trees have recovered enough before you shorten them again - don't want to upset your client )
