I found that using a simulator (a home PC with FSX and also XPlane) actually reversed some progress I had made.
The reason is that I was learning to fly the 'sim' aircraft and the simulators are not very good at the physics of the ground effect, the changes in control authority and the 'sense' you get from peripheral vision related to the flare.
In fact I have made a decision to avoid the simulator except maybe for some messing about with 'Nav' (which is a bit silly on the simulators as they tend to have the one obvious landmark standing out massively and then loads of generic trees and buildings everywhere else.
