I can confirm that we don't use new tyres for national league. There is no point there are plenty of decent used ones available. Recently had two paid maximums on tyres that had done two heats on each edge before starting the meetings. Personally don't see the benefit from a cost point of view to the rider a heat leader on £15 a point has his first 4.5 points wiped out buying it it's ok if someone is providing them but still think it makes much difference to the lads based on the tracks they are given kings lyNn has been the exception so far this year as it's been fantastically prepared
