I think (and this is just my interpretation of the original post) that what he's suggesting, if it were to actually work would do nothing more than fill out the already substantial field of the lightning sprints even more. As it then be adding those who have a D2 midget to the car count, verses only lighting sprints.

I don't feel like he's suggesting that the tracks start booking winged D2 shows in place of the winged lighting sprints(that'd just be ridiculous). My one concern would be that the D2 cars would need a push start, correct? I think for tracks that's one of the draws of the lighting sprint is that they're self starting. Thus the show is usually more efficient in the instance of a red flag, instead of having to push off the entire field like they do with regular sprints and midgets, the lighting sprints can just hit the starter and throw the car in gear, and away we go.
