Also, many RTO briefs states that after V1 you only abort for eng fires/failures or A/C is unable/unsafe to fly.
Sorry old chap - After V1 you would never brief to abort for an engine fire failure - V1 is calculated based on having sufficient performance to continue in the event of a failure.
However I agree with the unsafe to fly bit! But you are off the charts then so you gotta think on your feet, use a bit of experience (i.e "that looks like plenty of runway to stop on"), and hope for a bit of luck.
Well, If I got a stick shaker at rotation with plenty of rwy ahead of me I would personally have done the same. A stall warning is probably as unsafe as it gets....
Agree 100%
