To make the racing closer, you want the gap between the top & bottom riders to be lessened. There will always be new inexperienced NL riders stepping up, but if the league on the whole was weaker, shouldn't be such a task for them to achieve the minimum 2.00 average.
I'm sure no fans of these riders at their clubs would want to lose them, but if he likes of Lawson, Masters & Harris can race in the Prem as heat leaders, should they really be in the second tier?
If we can get to the stage where Prem heat leaders / top second strings race, Prem & Poland / Sweden only, then lesser Prem riders double up in the Champ, there would a lot less guests needed in the Champ, a lot less hassle rearranging fixtures around foreign matches, a lot more youngsters realising a Champ place is a bigger possibility.
Riders won't like it, some fans won't like it, maybe the likes of Poole & Glasgow would step up rather than run a Champ at second string & reserve standard (I've no issue with that). But something needs to be done to secure the future of the sport, carrying on as it is now, obviously isn't working.
