That is a new one for me, I never saw the fiber roadbed. This place always has a wealth of knowledge. On my layout l used both narrow tie and the wide variations. I would have used all narrow tie if I could have found enough to complete the layout. I had purchased a ton of roadbed before starting and as it turned out l had to use some gray sections, I painted those with black latex paint and when in place you will not be able to pick those out.
As Jerry mentioned, Happy New year to you all.
