My observation with very low weights is that the "pull the speeds out of the book without thinking" can bite the pilot very firmly if the sound stops near V1 .. especially if the operator norm is overspeed takeoffs.
Not a major problem to fix, but it does require some tailored practice in the box to see how the pussycat at normal weights and high overspeed takeoff schedules with a nice post-V1 failure becomes a raging tiger at min weight, min speed, max thrust, max aft CG, and a failure right on Vef and, of course, a low vis/ceiling setup. Mind you, those folk then never had a problem with a "normal" failure. It was interesting to see folks able to recover and then track out on the opposite LLZ after a few practice runs. Almost invariably, the first run was a loss of control situation which had to be frozen at an appropriate point in the sequence.
Granted the box may not model the point precisely .. but it does so to the extent that the pilot never forgets the exposure and the need for prompt action ...
