Pietersen lets his emotions take over too easily to be a captain, he can be unprofessional and uncalculated. Sure he may come up with a spark of genius on occasions but his captaincy would be sure to lead to inconsistency. Strauss is conservative but he is very intelligent and cool headed and is a great leader of men. Although he does not have a spark of genius he is in my opinion a very good choice at the helm of this England side alongside Flower.
