Scott, Not familiar w this software but think I know what i'm looking at (scale wise). Looks nice. I like the large curves - esp for the larger O scale stuff that requires 042's and 054's and the upper track plan. I'm 12-16 mo away from starting a build. Trying to maximize space is part of the fun - I think. I'm leaning Ross as well but still debating controller location, type. I love their 3 and 4 ways'. Enjoy the build and have fun,
Tom
