So, both designs are a folded dogbone. Do you care if your column is in one of the bone ends or do you want it to stay outside of your layout? What minimum size curve do you prefer? What orientation of the dogbone ends do you prefer in the room (long side or short side)? People here are willing to help, but don't want to recreate the wheel if you don't provide detailed information. The biggest problem with FasTrack is getting all the fitter pieces in the right locations to close the loops. This will also impact where you might be able to cut switches in for sidings, yards and industries.
