That'll do it.
. the only trees NOT damaged were either small,
Sorry to hear about that. But if there is an upside most of the marginal trees and limbs are taken out now so next time won't be nearly as bad. FWIW I have had some marginal success in the past with breaking off the ice with bird shot when I knew it would be a problem. Stand back 30 yards or so and let fly from a shotgun. A lot of ice falls off and damage to the tree is minimal. The 'treated' trees still suffer some ice damage but not nearly as much and I haven't had any of them go completely over. You don't have to get it all just enough to take off some of the load. Wear eye protection and shoot in a safe direction. Obviously this won't work if you live in town or a subdivision.
