I’m having a interesting and possibly surreal conversation where Stuntman Ronan and Chris Dore don’t experience line twist with a Belgian Cast.
So can I take a poll please?

Since the line goes under the tip and over the tip, if you look down the line from the tip, this is the equivalent to putting one twist in the line. Right shoulder casting is an anti-clockwise twist. Same with the Single Spey off this side.
Easiest way to remove it is to cast or slip the line to bang the reel a few times - but there are other ways.
However, who manages not to get line twist build up from repeating this cast? And who does?

Thanks, Paul
