I was reading on a CZ forum a couple of days ago, and they said that while the Timney and Jard triggers are great, you can just change a couple of springs and drop the pull weight in half on the CZ rimfires. Most said there's no reason to spend a bunch of money on a replacement trigger. The spring kits run about $20, if I really wanted to improve the trigger on mine I would try that, then if I still wasn't happy maybe try a replacement trigger. I'll risk $20 for a reasonable shot at saving a hundred or two.
