This year hull had a good idea, teams of 4 (mainly) british lads in 7 heat meetings second half.
I Think next year ALL tracks should have such a team, including stand alone CL teams.
They can be done at a local leval ie Newport, Swindon reading and Somerset one Group etc and could be done on the same day as the main between meeting those teams.
The teams would consist of at least one junior rider and the maximum of one PL reserve (who is riding in CL). and ALL riders must be british, or elagable to ride for the GB team. Also posably at least one "local" person, to ensure development of local lads (and lasses)
The reason this needs to be done is there is very little junior racing that is competative, they ride the same with people each time, and can learn little from that.
