I know Umberto would suggest that I download and try the them for free, but to be honest the trail period is so short that I can barely use it long enough to get a good feel for the performance.
Short ? You probably haven't understood how the Trial works: you don't have just 6 minutes of Trial, you have an UNLIMITED number of 6 minutes periods because, if you restart Flight sim when the Trial has ended, you have another 6 minutes of Trial. There isn't any limitation on the number of times you re-start the trial, and there's no expiration date also.
I can't think of a more extended Trial like this one, which is designed JUST for the purpose of flight simmers, because they like to try, tweak the system, restart, try again, tweak again so, it fits perfectly whithin this testing pattern.
Also, keep in mind that the Trial does not start until you enter in the scenery area, which is usually about 10 nm around the airport. This mean you can even make a complete flight arriving from somewere else, the Trial for our scenery will start only when you are 10 nm inbound, which should be easy to cover at normal approach speeds in less than 6 minutes, so you can even practice all approaches, if you want.
