Check out some a Walter Bennetts videos on you tube

I talked him into putting his mining videos on youtube a couple years ago. Watch one of his more recent ones with the Marion 7820. That operator is already swinging just before he pulls the bucket out of the cut. The bucket is practically behind the boom tip most of the time. That machine has I think, a 300' boom on it with a 40cy bucket installed. This is why you want the point to swivel.
