why not have 3 sections east/central/ west/ measure from dunbar to greenock as that takes in most of fanicers in the centre belt. 87ml in length split in to 3 x29ml sections. west wind helps the boys on the east side section. east winds then that would help west side. west section=greenock/cumbernauld. central section= cumbernauld/ morningside edinburgh. east section= morningside edinburgh/dunbar
