From a Club organisation viewpoint I think that 2 classes on 1 day would definitely benefit clubs as it would leave more dates free on the calendar for running club meetings, which are essential to the survival of any club.
When we first started racing a number of years ago this was always the format for the meetings - 2WD run first and then 4WD in each round and we even had 3-leg finals for the A finals which were staggered into the other finals and this was with 100+ drivers but the heats/finals were only 4 minutes long then and 3-leg finals were stopped when race time became longer as the meetings were too long.
I would agree with reverting back to this format of 2WD and 4WD at the same meetings and maybe alternate which class starts first at each of the meetings so that it is not the 2WD finishing early each time. It would also give sufficient time for a flowing meeting as we woud not have to keep giving a break between each round.
I do think that number of entries could also increase as drivers would appreciate the amount of racing they could have in one day. I understand that it could mean additional equipment for some but as Craig has pointed out the money saved on weekend events should soon amount to the cost of another lipo.
Definitely something to think about from a Club perspective.
