I am firmly on the Race Jacket side of the argument. It is far, far easier to pick out your own Team's logo on a Race Jacket, whereas the Team Suits are very anonymous and frequently you cannot make out the Logo because of Sponsors names and their logos.
I have always felt that way.
That is half the problem with Speedway. The Authorities are always fannying about with changing things that aren't important and ignoring things that are.
