I'm just looking at the survey style options on a Trimble TSC3 with Access. I'm just wondering what the differences are in "RTK & infill" , "RTK & logging", and "FastStatic"? Also which would be the best option to set it up with for collecting some shorter static sessions?
Thanks for the help!

The survey style, RTK & Infill, is for regular RTK surveying, but your base receiver is also logging data. If you loose your radio connection you can still continue surveying, but not in real time. When you download your data into TBC the program will process your data by using the data the base has stored. For this to work you have to fire up the job in RTK&Infill at the beginning of the session.
FastStatic is for static surveying only, setup a receiver at point (hopefully a known point) and other receivers (at least 1) at another point or points, the only data that will be processed will be for the times when the receivers are logging at the same time. Depending on the number of satellites they are all logging the minimum time is 8 minutes. After one session you leave 1 receiver on the same setup and move the other receivers. Leap frog style is what I've head it called, you should have redundancy on all of your points.
Not exactly sure what RTK&Logging is, would assume your base is logging data while you are doing your RTK work. base data could be downloaded and sent to OPUS for processing.
RTK & Logging is for doing Fast Static along with RTK. This differs from RTK & Infill, since that is truly for RTK & PPK in the situation you described above.

I might be wrong about this, but I think RTK and logging is just slightly different because RTK and infill has an automatic feature built in to it, I usual ignore this feature because it can be squirrely when you are getting radio and losing it. I control the PPK session at the rover, turn off the RTK infill session, turn on a PPK session when collecting in PPK during a RTK infill session.
The idea is that RTK infill can be started as PPK without shutting down the RTK infill session. This allows you to start the PPK collection as you are surveying. The problem I've run into is that the rover may recover radio and jump into RTK and you get shots that are really confusing when you download.
So I prefer to just shut down the RTK infill session and start a PPK session, collect the info, then when radio is available restart the RTK infill session and continuing collection in RTK. I know this isn't the "proper" way to do it, but I just got tired of sifting through RTK/PPK numbers on the same point. I will watch and if I see that I have radio while doing PPK, after collecting the point I will restart the RTK session, fix, and collect with a new number. Kinda of anal, but I guess I want more control and more redundancy.
RTK and logging I think is basically set up to do what I do anyway without the ability to automatically start the PPK session.
The base logs data and is available for static processing.
The terms PPK, fast static, stop and go static, static are basically all the same thing, nothing stops you from doing static at the rover with RTK infill, or PPK from a base collecting static data. The files are all the same when you download, I can tie to a CORS with a PPK session, there are no big letters in the file saying THIS IS A PPK SESSION AND CAN'T DO STATIC although OPUS is out unless you sit collecting a PPK session for enough time, then no problem.

RTK + data logging sets the rover to store the raw data as well as the base storing raw data.

I used to think that also, but I could never find a place in survey styles to allow the rover to log, only for the base. When you set-up the rover, it would never ask the receiver or DC to be the collection device. Haven't tried it in a while however

If you want the rover to store raw data; we never do. You just go to Rover Options and change it from RTK to RTK & Logging; the logging device and interval are on page 2. In the latest release of Access, anyhow.
The difference between that and RTK & Infill is that the Infill only starts logging when the radio is lost.
