They've tinkered around the edges for years with rising stars and whatever they were called beforehand, grading reserves in the championship etc. which led to Boxall and Armstrong at reserve for what was meant to be all season on 7 point averages.
Set a points limit and let teams build to it but by all means encourage younger british riders being signed first and foremost, if a team doesnt want a british rider they shouldnt be forced too but with the knowledge they will be signing a rider with a higher average.
