Don I'm not going to even try and answer that question. But hats off to you it is a great question and has been discusses countless hours in All sprint car areas not only with the NMMRA.
Some fans want to see the speed and show the wing cars present other want to see the driver wheeling the more sideways slide you have in the wingless version. Both ways are great fun to drive and I will gladly do either. My preference though would be with the wing the cars a lot faster you have better control behind the wheel you don't have accidents as often and when you do go bottoms up you generally have a little cushion for the first bang.
