Almost all of my CZs started as single action or I have changed to single action. And for the ones that are single action I have put the flat trigger on. I have tried a few different SA triggers like ET, PD, CGW and others but I keep coming back to the flat trigger. I also have sold two of my CZs to a guy I work with. The first one was a 75b SA with a flat trigger and shortly after I sold him a SP01 Shadow he had me switch it to a flat trigger. Then he bought his daughter an SP01 and had me switch it over to single action with a flat trigger. I currently have 17 CZs. And OP nice SP01 it looks good and sounds like a really nice shooter.
