My Suggestion is.
If the meetings are going to be on the same weekend then we need to have a long weekend if so etc
Saturday, sunday Monday, most people arrive on friday.
if easter weekend is out of the question and the long weekend is it then
Friday could become Scinteering and practise days.
Saturday will host pre 70, pre 65, pre 60
Sunday will host pre 75 pre 78 pre 80.
Monday will host pre 90, pre 85
Now, classes in the morning can be heats, and final in the afternoon and some classes can be taken out, and retain age classes for etc.
Pre 60 lightweight and pre65 lightweight can be combined depending on numbers heat 1
Pre 60 and 65 263 and over can be combined together. heat 2
pre 70 250 --heat 3
pre70 263 & over --heat 4
pre 70 125--- heat 5
under 30 allpower --heat 6
30 to 40 allpowers--heat 7
40 to 50 allpowers--heat 8
over 50 allpowers--heat 9
again depends on numbers there may be 2 heats for one classes, then after lunch finals
