Between 80kts and V1 I will stop for a fire, engine failure, smoke, structural damage, blocked runway....
If the call is GO, OR speed is ABOVE V1, I will continue the take-off.
That is what you've briefed, and that is what the other guy (we are multi crew after all) is expecting you to do.
So, there is no decision to make, because the decision needs to be made before V1.
