I use a combination of Ross turnouts with Gargraves flex track. When I started my layout over 30 years ago. The only sectional track was tubular. Even the Ross turnout selection wasn’t what it is today. Your building a layout using standard radius curves. The Gargraves flex track is more useful when you want long sweeping curves or easements. More of a scale type layout. The one benefit of Ross is how it looks compared to Gargraves. The Ross track is spiked and glued to the wood ties. Gargraves uses a web design where the rail slides into the ties. Nothing wrong structurally wise with that method. But if you don’t plan on ballasting. That shiny web stands out. I also think it’s easier to solder wires to the Ross track from the underside as it’s a flat surface
Your layout size isn’t huge. I would go with the Ross sectional curves. Many adopt this method and just use the 37” Gargraves on the straight portions or for slight changes in direction. If it’s just a matter of a few straight portions. I’d go with all Ross. You will not find a better guy to deal with than Steve. Any issues. You will be talking with not only the owner. But the guy that makes it.
