Derek -
I'm not telling you how to prune your tree - it's your tree. I just told you what I'd do if it were my tree. I've pruned all ours in that way, and they've turned out well. Since it was in the thread asking for pruning advice, I thought I'd try to be of help. I get my info from nursery owners, university profs in their fruit depts. , books on apple tree pruning, and tips / pics from some guys on here who don't post often anymore. Those gents are / were long-time commercial apple orchard owners, or nursery owners themselves. I pruned our trees the ways they recommended.
8" of new snow, huh?? High sun angle should melt it down shortly.
