Confused about hybrid and branch?

I plan to design a set of experiments using the B1850_CAM5_CN compset in CESM1.2.2. I got this spun-up restart file b.e11.B1850C5CN.f09_g16.005.rest.0501-01-01-00000.tar from the Globus endpoint. The experiment design is as follows:
1. Experiment 1: Restart the model from the above restart file and run it for 250 years;
2. Experiment 2: Restart the model from the above restart file, modify the source code for calculating the heat flux at the sea surface, and run it for 250 years.

My question is:
1. Should I use branch or hybrid for the above two experiments?
2. The resolution of the restart file is f09_g16, if I want to run the experiments as f19_g16, how should I implement it?

CESM 1.2.2 is my first choice, but I can also use CESM 2.1.3 if CESM 1.2.2 is not supported.

Looking forward to get any useful information.

Best regards,
KW
