What advice or experience finally made good landings click for you?

The biggest improvement i discovered was adding screens.

Three 1080p monitors, front and either side, make flying the traffic pattern (circuit) SO much easier.

In addition, an extra monitor or two underneath, running Air Manager instruments, make seeing the dials vastly easier.

With those bits sorted, actually flying the plane seems vastly easier, so you can concentrate on the task of getting a smooth landing.
