Been there, done it (recently), and will do it again.
Would anyone suggest that a pilot should not use all of the normal flight controls available to keep the aircraft in a stabilised situation during Takeoff?
I'll fly with that guy (or girl) any time, a well managed Takeoff in difficult conditions ...
And yes, Roll Spoilers operate assymetrically, and only deflect a FRACTION of the full symmetrical deployment available for Ground Spoilers.
