Why tubular track?
In my case I had stock from previous layouts
sounds good more like real train IMO
works good with Magna traction
pretty cheap
still readily available as are switches
many turn radius available
many switches available
pretty easy to cut to size if needed
draw backs are (some)
no roadbed
cut hands I my case even with gloves
Not a real or prototype look again IMO
and probably others
that said all track systems have good and bad points
