My neighbor told me they were going to have their tree professionally dropped, and wanted to know if I needed any of my trees dropped - I replied "no, I only drop dangerous trees". I then asked if they were going to limb it up before they drop it because it has a lot of back weight, to which he replied "yep". You can imagine my surprise when I returned home and saw they were over 95% committed, with the limbs still on and no ropes.
Skip to about half way if you're antsy.
