Leica and Civil 3d Workflow questions

I am about to update our DC's to Leica Captivate. I like the new linework functions so the guys can see it in the field and the ability to export the .xml to c3D with the style sheets. Also our CS15's are beat to hell and need replacing.

Right now we use PConnect to do our linework. So we process and adjust the data in Star*Net or Infinity and then insert a .txt file into C3D. Then run the linework with PConnect. With the Leica solution I believe that survey figures are created. So here are a couple of questions.

1) Is there any major advantage or disadvantage to having survey figures instead of polylines?

2) Say the guys run a traverse and do all their side shots in an arbitrary datum. Later we collect the GPS data and process it all down and adjust it and the traverse in Star*Net or some other program. How do I get that data into C3D and keep/update the figures to match the new adjusted points? Do figures automatically adjust if the points move?

Most of our work that we adjust is transportation work...We set a couple of azimuth pairs and run a traverse between them. We often GPS after the total station work just because of scheduling of the equipment. We almost always take our sideshots as we go instead of running a traverse separately then going back for the side shots. I used to process this all in Carlson which was super easy because they use angle right and I can just change the starting coordinates. Unfortunately Leica only outputs traverse data in azimuths so it's a pain. I recently started using Star*Net which doses not seem to care about azimuth or angle right data. Any ideas or suggestions on workflow here using Leica equipment, processing with something like Star*Net (Infinity kind of stinks. Is C3D least squares any good?), then drafting in C3D?

Thanks
