I like the height of the 60l drums, as your body is upright, and the drum is low enough to use a knee to hold a lever in lock position.
Double rim lock wide rear rims was the apprentices job when doing my time.
No fancy tyre machines, (not that they can do double locks any better).
Knocking the last few inches home with the rubber mallot is one sweet moment.
(insert filthy remarks here-------------)
