You said you wanted the traction in the front, while sort of correct you want the tires with better traction in the rear no matter what. The end game really is four *good* snow tires. Keeping the back end of the car behind you is a huge issue with mismatched tires in the winter and rain. It allows the rear to swing around. The theory is with bald fronts and new snow rears is that you can never get going fast enough to have understeer be an issue and the rear will stop the car.
