I certainly consider myself to be old fashioned, but I like two stage triggers on hard recoiling bolt actions.
I feel that the definite first pressure and travel gives one time to settle the breathing and prepare for the shot. It also allow one to back off and not fire.
I feel sometimes with a single stage trigger there is a tendency to take the shot anyway even if one is not fully comfortable because subconsciously having applied some trigger pressure it is difficult to let go as nothing is going to noticeably spring back to a safe position. Sort of like half turning on a light switch, it is not a natural thing to do. So one continues and anticipates a bad shot or pain and consequently flinches.
I believe that 2 stage triggers are available for the CZ at about $ 40 US it may be worth changing it out and see how you get on.
