should harness racing drivers have minimum to maximum weights and races be handicapped according to weights like i.e 10kg = front row --10kg back row etc or +10kg down 1 class would like some feedback as i notice ever so frequently that female drivers (who are natural lightweights are always winning putting the others at a disadvantage - should all drivers be for example 60kg - 90kg in weight to drive at races and be handicapped for weight in that range?
