Sounds good - the 80 ~ 21.25" and the 106 ~ 28 on the outside rail edge to outside rail edge.
You can use the big curves- the 106 are great to replace a long straight with a "snaky" of gentle curves
Here's what is would look like using 8- 106 curves are the O54 & O42 - about a 13'6" long layout - 6" center rail to center rail spacing
