Replying to 4frnt Devastator 20/21

I have a stiffer ski thread going and one of the skis that was mentioned and that was already on my list was the 4frnt Devastator 20/21. Does anyone one the forum want to shear their experience with the? How do they perform in rough conditions? On hard pack. And in thight places.
As mentioned in the other thread I am looking for a stiffer but playfull ski that works better than my Line SFBs at higher speed and in less ideal conditions.
