only trouble with cadwell will be getting a sunday track day in the summer. most weekends have bike or car race meetings on sundays during the season. may get a date later in the year, sept or oct.
weekdays are easier (and cheaper) but most likely wouldn't suit most folks.....
i really don't mind what the majority decide is best. will do whatever..
blyton would be cheaper and more available dates on a sunday, just you don't get the track experience of driving on a "proper" circuit as used by bsb etc
