Have been having similar discussions with some at our local track. As VTA is our primary class, I would venture that PnS is a little less effective, as maintaining corner speed is vital in keeping up your momentum. With the weight to power ratio of 17.5 and above, there is almost no need to maintain corner speed as your acceleration curve is fairly ridiculous. That is the main difference between real racing and RC, is the acceleration potential and top speeds. Real cars are not running 500+ mph and getting there in 2-3 seconds.
