Good post Kevin,
The BEL should be reduced in size to maybe 8 teams and run on the same format as the Swedish elite league.It could be run on say, thursday night if the other main leagues took different nights you could then have your top stars available for all matches and run extra GPs as well.With more earning potential you can reduce wage bills too as the top men can ride 4 nights a week and a GP.
The PL could be used as a feeder or training scheme,but due to league set up currently in GB I dont see the promoters of successful clubs being happy to release star riders.Maybe a better way is to encourage dual teams, one in EL one in PL on the same track on alternative weeks.
The main problem with rain offs cant imo be solved until promoters become stadium owners so their investment can remain as an asset. At the moment any improvement is not in the lease holders interest as promoters only hire facilities.
Just a thought or two.
