Sour grapes I’m afraid. The Fitasc committee are obviously concerned that Supersporting is impacting on their revenue.
For me the two discipline are only similar in some ways and not a direct copy one of the other.
It’s a shame as I do consider the old system Fitasc sporting properly done to be the “Rolls Royce” of clay shooting but it has become so expensive of late as to be prohibitive for some people.
Supersporting is more competively priced and is enjoyable but not the same as Fitasc - no gun line restriction, no move the gun before seeing the bird penalty, a series of stands more like English sporting rather than a Fitasc parcours layout and many more rule differences.
There are only so many ways you can throw a clay into the air - you just can’t expect to copyright it!
