Could you tell me in what way the Premiership keeps British Speedway alive .Do the heavily subsidised the Championship for instance?

Half the championship heat leaders ride because they can afford it due to the championship, I’m not telling people they have to jump up, it’s their decision. I’m simply stating is the premiership doesn’t run then watch speedway further fall. 

Presumably the championship are trying to address the issue that has now blighted the Premiership where the outcome of the league is clear before a race is run If it spreads the better riders throughout the league and stops the top 3 or 4 from signing effectively 2 number 1's then I'm in favour 

What about giving the young american Slater Lightcap a go at reserve alongside Loftus ?

There is no one league that keeps the sport going as both have similar examples of crowd sizes, kudos in winning competitions, and public awareness... Maybe next year we could have a Premiership, but at a reduced level...? Ipswich, for example, could keep Emil (presuming he wants to ride over here), and then release Doyle, Brennan, King and Ellis to spearhead four teams in a much watered down league... You know.... For the good of the sport rather than selfishly looking out for themselves, particularly as they have the financial backing to do that etc, etc, etc... .....

Problem is in the current set up without massive sponsorship nobody would want to get promoted .
