I can't see that working bkm, because :
a) If you say no P & R for 3 years and then promote the top 2 in NL1 (providing everything else is in place) then what do you see happening in the two years in between this year and the year of promotion? Teams will not be unduly bothered where they are in the league as they build up resources (money) to have a determined go at the 3rd year. So, you may as well leave the franchise system in place.
b) The franchise system is as good as in because all the SL clubs are wanting it for their own greedy benefits plus the head man Richard Lewis is all in favour of it. Next year will be the last year Haven, Town or Barrow will have to get into SL on merit. After that we will all become mediocre part time National League teams. Even being top of the NL1 won't mean a lot after 2008.
c) Haven may have a new stadium in 3 years time, maybe not, but as it as been pointed out our clubs will need more than new stadiums if they want to get into SL. Both our clubs and catchment areas are not big enough to support either of our present clubs in SL. I think more and more people are now coming to realise this. We all have to make our minds up if we want to be mediocre NL teams or try to find a way of combining (not a merger) in some way to put in a joint team in SL like Les Catalans in France.
There are and never have been any conspiracies afoot to keep Haven out of SL the reason you are not there is through lack of finance, a stadium, and major sponsorships. The team on the field is now and will be in the future just a small but important part of getting into SL together with all the other parts of the package.
