Firstly I must confess that I enjoy a good bit of euro nymphing.
One criticism of often hear of euro nymphing is that it's 'lobbing' not 'casting'. My response is that bad euro nymphing involves lobbing but good euro nymphing involves casting. I work on my euro 'cast' as much as I work on my traditional cast.
The video below I am casting a 2.5mm single tungsten fly. So not a great deal of weight and would be quite hard to lob accurately.
I was out recently and a friend got some footage in a light where you could actually see the euro leader which is rare. I would be interested in opinions on whether the motion in the video is something resemblant of a fly cast?
Whether or not it's fly fishing or not is a discussion for another day
