Thanks for all the replies! I am not worried about time as much as learning and having the experience of doing it. As I design my layout I may order some supplies and get a feel for it. Turnouts still seem daunting to me...so I need to do more research on it.
I went down this rabbit hole when I was researching layouts and turnouts and saw videos on handlaid track.
This is my layout design so far (16'x8'). I used all Atlas track for the design except for the crossing which is a Lenz in the proper angle. According to the program it is 999" of track...so very manageable. There are a few areas for custom cut flex so I think that would be good for handlaid track also.
