3/4 wrap: yes. Full wrap: sometimes. Half wrap: sure. They all have their advantages. Being able to cut everything from the safe side of the tree is a major bonus, but smaller and narrower is nice too. My main work saw has a 3/4 wrap, so I guess you can sort of see where my loyalties lie. I am a fireline faller rather than a commercial faller, so I'm mainly concerned with safety rather than saving cash on the stump, which means that my 3/4 is for speed and safety.
3/4 saved my bacon the other day when a rotten, burning snag sat down on my face cut -- I just powered through, watching the top, 'til the bar was free again, then, without moving, I flipped the saw over and dropped the beast. That would have been uncomfortable, at the least, with a 1/2 wrap handle. If I'd had to walk around to the other side, it may well have fallen on me. It was not a normal tree, so normal falling rules didn't apply. I was glad of the extra safety margin I had due to my 3/4 wrap handle when the rotten hulk fell about 15 degrees off of my planned line.
