I guess it depends on whether your going to the game or not. I spend most my Saturday's watching Young Munster RFC, so evening Sat kick offs suit me.
I go to games at Goodison Park when there is no rugby match. Just recently was at the Norwich match, travelled to Dublin to make the lunch time flight and returned on the evening flight, getting home at 11pm. Anything other than a 3pm Sat kick off and I'd be screwed, or need to book a hotel for the night.
Love Goodison under lights though, at it's best then imo
