I don't know where this myth about the adverse camber at Rye House disappearing came from. It's still there, believe me.
Chris is spot on. There is very little home team advantage when you build a weak team. Speedway is very much a confidence sport. If you're on a roll you can believe you can beat anyone.
Rye House used to be a track that teams feared, many were beat before a wheel was turned.
Edinburgh and Somerset have that reputation now.
