Four Questions. Need some guidance on this.

1)I own GE Pro. My question is : Do we really need to use the Megascenery/Mega City sceneries as well??? What is the advantage of using both if texture are so good in GE Pro, aside the from eating on my HD real State when installing both.2)When are the nightligt sceneriy for GE Pro coming???. Can we use the Zinertek UltimateNight Environment Proffessional, instead????? 3) Where is the best place to store the land class file ????4) Where is the best place to store the afcad2 files. In the same scenery folder of the aircraft, or somewhere in the Scenery folder in the root of FS9. Would Appreciate your advice/recommendations.Edmundo Cardenas SVMICaracas, Venezuela
