Interesting topic and just another black hole in the world of Speedway and why guest bookings need to stop.
It has been brought to my attention a few times about riders who start off poorly drop a point or two and pick lots of other meetings elsewhere.
Not knocking anyone for trying to make a better living, but a few riders 2008 2011 stick in my mind of blokes who started badly and ended up with twice the PL fixtures....
There has also been the issue of riders doing it to get team places elsewhere, which I am certain is nothing new
I guess you just need to be careful who you sign
