Two leagues made up of riders available following the demise of the Premier League and loss of the very best riders seems the most sensible, especially since only one of the leagues will need to support full time riders.
Don't forget, this situation has been brought about because the majority of the BSPL promoters of whom the majority are Championship club owners didnt want the existing league set-up to continue (exit Mr. Louis)
Also, given the BSPL/ACU/FIM structure, such a move will not be acceptable to a good number of those remaining riders given that Nora meetings would be the only ones they could ride in anywhere in the world speedway/long track nor grass-track including GP2/world under 21 and other junior championship.
All those folk who wanted one league may not be getting their wish, but they are getting the best solution to providing speedway with the less number of riders available - We should always be careful on what we wish for!
