Thats an interesting idea Leyland.
Of course you can use the Flexi-Track anywhere and in any length to fill in troubled spots but I'm definitely not in favor of the look. On my Layouts now I custom modify tracks to fit any variation that I need and they turn out great as they blend in perfectly and can hardly be seen. This proved to be perfect for the Gray Elevated rails as they don't come in shorter sizes.
