Sunday at 7 utc would be the best option imo.
Although it will be a hardcore weekend.
With 16h race ending earlier in the day, and a local LFS league race ending at .. 6 utc.
Okay, I'm moving in a new house... the 1st of November, so it will be very hard for me to find a decent computer with a decent connexion for this one. It seems to be the end of the season of me.

We go back an hour on saturday night (as does all of Europe). So it will be at the same time (8pm in Britain) for us, which i think will be better - certainly less confusing
