I'm in the let them lay camp, but with a purpose. You're going to have a mess of tops laying around to deal with no matter what. Might as well turn lemons into lemonade. There's going to be several years of new growth coming up from the floor so you will have new deer moving in. That's a given. Instead of letting the chips fall where they may, use the tops to engineer the type of herd and hunting situation you want. Drag them to strategic spots to layer bedding, redirect trails past ideal stand locations, create funnels, shield your own movement, etc. Ideal would be if you had enough to have scattered "neighborhoods" of bedding with a good plot within access to them. Even better yet if you could wall off the "residential" area from the outside so the deer, especially older bucks, aren't disturbed every time you go in and out of the woods. 100 mature trees over 30 acres gives you an incredible opportunity to create a deer haven. You are blessed.
