I was at Z-Max for the very first 4 wide pass, the year the track was opened for business. Went back twice to watch the 4 Wide Nationals. Is it a spectacle? Yes. Is it cool? At first, yes it was. But the novelty wore off pretty quickly.
There were a couple of reasons I grew to dislike the format. First of all, it's very hard to focus on the staging procedures, or see your favorite car very well if it's in the 4th lane furthest from your seats.
Most importantly, I felt the reduced number of 4-Wide laps on Sunday, diminished the show. If you have a full 16 car field on Sunday in the 4-wide Format, you'll see 4 First round heats, 2 second round heats, and a Final Round heat. With two wides, you see 8 laps in the first round, 4 in the second, two in the Semi's, and a Final Round. So, you'll be seeing 7 total laps for a full field, 4 wide elimination format. With the traditional 2 Wide Elimination Format, you'll have 15 laps per Pro Class on Sunday.
Yep, I'm one of those old-school fans, that would prefer to have more individual passes, than be "awed" by the spectacle of multi cars going down the track at the same time.
