With new O-gauge layouts I can get individual lengths of straight and curved (various radii) sections or I can go with flex track (I'm considering Gargraves 3-rail). It seems as though flex track is more economical and has better electrical characteristics but may be hard to design in software and then lay it out perfectly to match the design in practice. As this is my first layout I thought I'd throw this out to the experts. What other brand than Gargraves would should I consider? Tin plate or stainless steel (finished basement)? Wood or plastic ties make much difference?
I have a plan but it's all in tubular and I want to change the track before I solicit comments.
Thanks!
