I use REX (Real Environment Extreme) 2.0 Overdrive for weather and Aivlasoft's EFB for flight planning, but REX has a flight planner that you can use, if you want to. I prefer the more in-depth EFB which allows you to input SID's, STAR's, and Approaches and so makes for a much more realistic planner. I think FSC does the same thing, right, Mark?
