Hi All,
I think we should look at all the classes and make sure we cater for as many riders as possible, without having 20 classes with 3 riders each. The Junior classes seem perfect and the splits between classes allow for juniors to get on faster bikes as they get older.
The senior cag class A & B seem perfect as well. The class C might benifit with a minimum weight limit to stop a 45kg 16 year old from running away with it. Something like 90kg minimum weight for rider+bike and gear as at the end of a race (i will bring my bathroom scale along for this).
Senior D has the power restriction as Junior E, so it will logical to allow the younger and lighter riders of 16+ with 11hp bikes to ride in this class. So no weight limit for this class, but still the 11hp limit. This way the younger riders that don't move on to other formulas have a class to race in with their old bikes. This will also be a good class for the lightweight female riders as 11hp with 50kg make for fast laptimes.
Senior F can be scrapped as there is not enough interest in this class.
Open class should be left as is, but we can also impose a weight restriction of 90kg combined as in class C to make this a real senior class and stop 45kg riders from running away with it.
I agree with Clifford that if the open / D class is big enough, you will always have a dice. A 16 year old weighing 50kg on a 11hp class D bike will give any senior (90kg combined weight) on an open bike a run for his money (will beat me any day!).
This way we cater for all the ages and weights and still keep the racing fair? from the sideline the open / class D will make for good racing as all the riders will have almost the same power to weight ratio.
I've made the combined weight 90kg as to include Andrew as the lightest rider in senior open.
Cheers
Andrio
