There is no official V1 rivercruise (like the other collegues mentioned). However nothing stops you to make your own decision speed which would coincide with the published rotation speed in a light twin - if you are not at a speed above red line at a certain point of that runway (accelerate stop distance is what you would look up and refer to in the POH), you should abort. This is were a balanced field length would count towards the pilots favour (this is a weight factor obviously). In an unbalanced field, you will land in the sticks, there is no way around that if anything goes wrong. Eros however should be just long enough to accelerate and stop (in standard conditions) if it was considered and given some thought prior to pushing those levers to the wall.
