due to the size of the event, why do we need a hard and fast rule, MA should allow the event to be split to suit the clubs running it, so you can run pre 78 down, pre 78 up or the whole lot, then you can run titles where they will gather the most competitors, second you could run them bi anually, pre78 down one year, pre78 up the following and then a combined event for the third year over the easter weekend somewhere, when the event is split you could add more age group events and then change it up for the combined event. Why cant clubs choose even to run age groups in say just pre 85 or just evo and not this singular pre 75 mentality, clubs could then promote different eras for their event
