Hi Stefan ,
I think that just means it's easier to see (and to measure and react to ) what would normally be hard to see. As in an engineering "gauge "measures things.
I started going sideways a few years back when teaching folk double hauling then I discovered that Joan Wulff had put out a video doing the same thing . I think we are deffo on the right lines with that one .
Should have said that I also often just ask people to put the rod down too , and then just go through the hand motions. That's interesting. Especially asking them to talk you through it .
The problem is though that often they are not doing what they think they are doing and also they don't have a line to show them what would happen if they were casting for real.
What is REALLY useful I,ve found is to get a friend (or someone they trust like an instructor) to watch closely what is going on and then demonstrate what they are actually doing .
Cheers for now,
Thanks again,
Paul
PS: Spot on with the pick up and lay downs .
