i think a bit of each. any point to point diorama becomes a chore to me. the little kid gets a great deal of pleasure out of watching trains go round n round. i have no interest in photography. some little bit of operation will break up the circle running, but if i only shift a car or two i'll be happy.
for what it's worth, i have assigned myself the following guidelines:
1/3 track hidden
1/3 track above an imaginary benchmark (say "0")
1/3 track below an imaginary benchmark (say "0")
i like the idea of a runaround track, but struggle to conceal its beginning or end. won't mind one turnout showing, but would not like views of both.
hopefully scenery, rocky coastline, will offer view blocks from the entire trackplan being seen in one fell swoop.
