Those that pull flights using the light system always cut the top of the flight of to allow the flight(quil) to die first, and then they would pull the flight several days later. Alot of top fanciers in UK now using the light system with huge success when many thought it couldnt be done this side of the globe with success. Alot of people put high priority on young bird racing which is a change of the past on where young birds was deemed as only training, for the future. However with big money prizes in futurity and breeder buyers, young birds in affect has become a huge priority, and those birds who win the nationals or combine(usually roughly around the 250 mark) racing as young birds, are receiving the same respect as what the old birds of yesteryear was, and rightly so. And theres nothing more exciting then young birds on the dark or light coming home from a race 5-6 up sometimes even more, and trapping like bullets!
