Had a CZ once with the single set trigger, and I'm not a big fan.
Using different settings for different types of shots means I have to think more than I am often capable of, in the circumstances in which I have to take a quick shot.
Much better, I find, is to have your trigger adjusted so that you can take a shot without unnecessarily moving the gun, while not scaring the daylights out of you when you touch the thing and it goes off. I've found something between what you get on an off-the-shelf rifle and the single set works in all conditions and allows you to practice easily and consistently for all conditions.
