Jeff's point reminds me that I've thought for a while now that we could probably move Clubman to Saturday and get much bigger grids since at any given event it's already half F4 bikes, anyway. ESS could naturally go with it.
Since most Clubman "big" bikes are only competitive in Clubman, it probably wouldn't make too big a difference to those who ride them (I've been one of them, myself), and they might appreciate the price break.
However, I do get the impression that the Saturday schedule is already jam-packed as it is. And the relative peace-and-quiet of the Clubman race on Sunday makes for a nice late-morning break for those who don't race it. But if we could fit one more sprint into Saturday, moving Clubman and ESS together might put a lot of bikes on the track (that would otherwise be loaded up in the trailer) and more than offset the reduced fees per entry for the club.
Just a thought. Make what you will of it.
