Well Hoppy, as you well know, if everyone has done their jobs properly AND you are at performance limiting weights (masses), then it's really and truly dicing with death NOT to get airborne. There are so many variables - stopway etc etc
However, (there's always one isn't there) if you're light, V1/VR is unity you get there quickly (like ferry flights on a wet runway where you're committed to a full power take off perhaps), you've probably got enough runway to stop anyway. The key phrase in all this is:
"Performance Limiting"
Emerald Airways 748 (I think) is a famous example of what not to do and get away with it - you'll always hear of some exceptions.
