737 flapless take-off successful in sim.

I am not an aerodynamics expert, just a line capt.
Had some time left on our 737-800 simulator session the other day and tried a few take-offs with clean wing:
High TOW, appropriate deration for a long runway.
With normal rotation technique (for an next generation 737 that is), and rotating to approx 14deg attitude, pitch stays just below the PLI.
The roll must be longer, but the take-off was successful. Not even a stick-shaker.
Rotating too fast and further than normal triggered the stick-shaker for a second, but was easily recovered by lowering a degree or two.

I do not know whether the software or behavior of the simulator is accurate, but considering its generally very realistic behaviour, I assume it is.

Surely severalMD-80 pilots must have tried the same experiment in their simulators since the likely cause of the Madrid accident emerged. I may have missed an earlier posting, but it would be interesting to hear the results of their tests.

Perhaps the 15 years of development between the MD-80 and the 737-NG make a difference?
