Yeah, well I'm a little nuts, lol. Having a backpack blower on your chest actually evens out your weight distribution, kind of how carrying a bucket in each hand is easier than carrying just one. The only problem is you have to bend the blower tube back kind of hard (I take one tube off) and it can get tiring. That and you get some exhaust in your face.
You can adjust the range of the chute on your Billy Goat with the cable adjuster down near the chute you know. I have mine so that it blows down and scours pretty well when I hold it all the way down.
