Matt-

.......Got to go to a meeting, but, I will get with your post later, sounds like there is some fog lifting in there for me......

Not only for you, I found as I was writing my incubator was on overdrive. My above post is just stating things and my assumptions. When I look at the onplane wrist action diagram of 2-K#4 have a look at the swivel joint and how underneath it Homer shows an arrow labeled 'left arm'. It can only be my assumption that the swivel then becomes a swivel of the 'entire left arm' as apposed to that of the 'left forearm' with the vertical flail action of 2-K#5.
