Use of the FS9 B737-800 in FSX

Hi,Probably like many others, we are waiting for release of the PMDG B737-800 for FSX. That might take some time but... we have a full size MIP plus Project Magenta so we realy don't need any cockpit visuals. Just the flight model and a way to store the weight & balance from Topcat. Somebody told us that in our situation the PMDG B737-800 for FS9 would work perfectly well.Can someone (preferably from own eaperience) confirm that this is true and if so, suggestion on any special trics on installation would be highly appreciated.Thanks,Dirk van Tongeren / Benno Groswww.b737sim.nl
