Sheeting a single alignment that has two pgl profiles

Another reason I want to store my PGL profiles on the centerline alignment is for the annotation of the profile.  If I were to store the profile on my offset alignments and then project it to the centerline, I end up with a chorded version of the real profile and it wont annotate vertical curve info (because its now a streched and skewed chorded version of the real profile).  This projected profile works great for modeling but not showing the contractor the actual profile info.

I agree with this.

We are required to show a number of profiles, and they all need to be annotated off the baseline. For the plan set we are required to produce, it doesn't matter that I am displaying the profile of the left EOP, it needs to be stationed along along the BL.

As an example, I consider a ditch line profile. We know that the ditch line will not be exactly as long as the baseline because, when the baseline curves back and forth, the offset ditch line will be longer or shorter than the baseline depending on whether it is on the inside or outside of the curve. The people reading my plans do not care. The ditch starts at station X+XX and ends at Y+YY, and the grade shown along the ditch needs to be based on that algebraic station to station length, not the actual length of geometry. I also need straight line segments, with defined PVIs - not a fuzzy projected profile. Let's make this even better, because I often need to show ditch profiles above or below datum for plans readability.

It sounds as if, to properly display this type of design data on my sheets, I need to define all of these profiles on the baseline. But doesn't that defeat the entire purpose of modeling?

Nope, because you can project those profiles from the baseline to each offset alignment you need to set a point control on.  Keep in mind when you project a profile with vertical curves the projected profile is a chorded line string version of your real profile on the baseline.  It's good enough for modeling though.
