I think you've found the silver bullet.
Still charge £18 or whatever.
Give us a 10 heat match.
Interval after heat 5.
Then charge the wobblers to use the track till closing time.
- promoters get more income
- promoters pay out less in points money
- punters get to see a match plus the wobbler entertainment
- riders in team have fewer rides and so lower costs
- riders in teams can get off sooner to catch their flights or drive to their next meeting
- wobblers get to practice on all sorts of tracks
This is the saviour for UK speedway.
