I would have no issue with YC at the next stoppage. IF that means the person being YC'ed is also a try scorer - so be it. The card is my option, not the teams. They need to play what is infront of them.
But if I am going to YC, then any advantage has to be fairly likely to accrue. Unlikely to be playing advantage for a PK & YC offence toot far from the try line, then the advantage over call is when a score happens. So the situation is highly unlikely to occur. If you are playing advantage for an offside, 40-50m from the tryline, then I have to ask - why YC? And what possible advantage was "on" that you didn't stop it and give the card there and then if it really was justified?
