long ago I decided on 072 so I could run a 700E I was restoring at the time.
The 072 worked out well and the gradual look of curves was appealing.
I still managed to make 2 mistakes that did not reveal themselves until many years later:
1) As I had a 2 track mainline, some curves were too close together
2) some scenery was too close to the curves.
These things did not emerge until I bought a Lionel B&O 2-8-8-4. The engine ran extremely well on the track but there were a half dozen or more issues due to points 1) and 2). I eventually sold it. In 1990 when I built the layout I could not envision owning such an engine. Way too much overhang in front!
