All proposed days are good for me, assuming same race times repeated from Season 1.
My thoughts on tracks:
Sebring - Good choice
Fuji - Terrible 3rd sector. Gets a lot of dislikes from majority. Also possible gpx problems.
Mid Ohio - Good choice
Le Mans - Unless we can find a modern version, '91-96 would be boring to repeat again.
Watkins Glen - Very good choice
Nurburgring GP - Not a fan
MoSport - Very good choice
Rouen Les Essarts - Good choice
Laguna Seca - No
Monza - Good choice
Spa - rF1 conversion one is barely OK
