I quite like the cable tie idea, I'll have to try that. I usually use my thumb on the stay to find the high/low spots.
In case you don’t know the turn the wheel around trick: If you turn the wheel round, it'll tell you if you've got the wheel centred. If it's in the same place when you turn it round, it's centred. If the wheel looks centred in the frame but goes off to one side when you turn it round, that probably means the frame is lop-sided.
