I agree with Geoff on the 583 being for novices - from 2006 onwards.
Anyone who has competed in DD in 2005 (without whom, there would be no series) should be allowed to choose whatever class they like, regardless of experience etc.
However, if they then leave the 583 class at a later date, then they can't come back in.
Just like in 125 gp's etc where they age limit came in, but current riders over 25 could continue to compete, until they moved on - thus preventing them from returning to 125's again.
Something like that should be in the rules.
