Yes, it is special, the way Bruscella & Chiarappa shoot here.
After shooting a "fermata a 9 intrecci in 3 sfondi", follows usually a fermata with 3 controbombe
But normally, the salutes between 3 controbombe are not used. But it is nice to see it!
Only the Scudo brothers shoot always that way in combination with their "Bomba Regina".
