I like some aspects of both sims. I like the historic flights on FS9, as well as some of the planes, ie the Wright brothers flyer that you don't have on FSX. David Grindell (I hope I got his name right) is converting a lot of the FS9 planes so that they will run on FSX. Ford Tri Motor, Jenny, Spirit of St.
Louis, to name a few. I like the graphics better on FSX. If you have to reinstall either sim, FS9 is
easier to do so. FSX was a real bear for me to reinstall. I has to talk to somebody in India or somewhere over seas to help with the installation. Like one of the guys said previously, fly the one you like. Thanks!
