Ken,
Of all the different layouts you have designed and engineered this engineering is the best. I never alter any of your great design work, in this case I would add the appropriate Command Control FasTrack switches to your layout design engineering, simply because I love the FTCC Switches so much. You would however need to allow for transitioning in and out of the FTCC Switches in some area's of this incredible layout.
As usual incredible layout Engineering design work by a Master Layout Designer!
All the best
