Climb (fine pitch) prop - shorter takeoff distance, faster climb, slower cruise speed for a given RPM.
Cruise prop (coarser pitch) - longer takeoff run, slower climb performance, faster cruise speed for a given RPM. You shouldn’t have to pull the power back as much, or maybe not at all to cruise at your desired cruise power setting.
Coming back to the airport, the climb prop should slow the airplane more quickly when you pull the power back or off than the coarser cruise prop.
