Well, now I’m half-convinced to just start over with P3D v. 5 with the new CS 757 and L1011, both favorites. Not quite sure what “compatible” (e.g 737), II and III mean, but I’m sure it’s around here somewhere. The only question left is which version of P3D to get. I’m assuming 5, of course, but not crazy about the watermark on the academic version, and not wild about $199 for the pro version. But have I got the pros and cons figured out correctly?
