You can leave longer skid marks with the disc brake system. Once the tires start to lock up, it doesn't matter how efficient the braking system is- - - - -the traction between the tires and the road determines stopping distance. Unless you're planning to haul full gross weight down steep grades on a regular basis, the original brakes should be more than adequate for practically all of the driving conditions you have described.
