Agree completely with tyreman regarding those running two classes.
I don't understand the 'if they wanna do two classes, make them find a stand in Marshall' posts.
It's normal around regions all over the uk to have drivers competing in both 2wd & 4wd classes. Just because we happen to run both on the same day shouldn't prevent it... It's not the drivers fault.
It can only become a problem marshalling when: a) you qualify at the bottom of one class & the top of the other, b) you're placed in different ability heats for each class, or c) the race organisers run the finals in a funny order
