I agree too Earl - one thing I have yet to wrap my arms around is how a 'big' track effects this. My experience is mostly limited to tracks like NHIS and LRP where you are talking 1.5 miles and 38-40 cars max. Just one look at the ITS/ITA proposed combo at the ARRC - and the immediate response - is where I am coming from.

Having said that, even though I love the ITS/ITB and ITA/ITC groupings - because I have been in ITS and ITA. I watch the top ITB guys try and race through mid-ITS guys and I know they get frustrated. Same goes for the fast ITC guys and the Mid-A guys. I just feel the power differential between 2 classes makes for better racing.

FWIW, in a track like LRP - in a 15-20 lap race - ITS is just about to lap the ITB leaders when the checkered flies...
