I raced both classes,so if you think you were rushed of your feet with 7 races try 14.
My decision to do this anyway as the more i race the better i get.
Happy with the format and mass starts,makes the heats more interesting plus you have to mass start in the finals so its good practise in the heats to mass start.
Thats the point of the heats isnt it, to iron out any issues with car,starts ect so that when the final comes you are prepared.
Happy with the 6mins and the new format.
