I think it's like golf where the equipment that the pro's use to optimize their game, isn't necessarily the best equipment for the average person. Blade irons help the pros work the ball around trees and what not, while an average golfer will just shank them into the tress and is better off with a more forgiving cavity-backed club.
I try to first may the car as forgiving and easy to drive as possible first then tune it a little tighter as I improve and need the car to do something different.
