I don’t seem to be able to pick a good visual clue to line us up straight
This I have to work on a fair bit with FO's because of getting used to the seat change.
The way I teach it is to look at the sides of the runway in relation to each other.
If it appears that they are both pointing in the same direction move in the oppersite direction.
If one is straight and the other at an angle move a very little in the oppersite direction its leaning.
When one side leans one way and the other side leans the oppersite way you have pretty much cracked it.
Once in the flare its focusing on the end of the runway.
