You and I seem to be at odds these days and your last statement is no exception. Heavy bolt lift is not a "feature" of cock on opening, it's an artifact of bad design. I clearly can't convince you of anything, but if you get a chance, spend some time listening to Ted Karagias who owns American Rifle Company. He's one of the most intelligent, gifted and generous engineers I've ever met. His generosity in sharing his knowledge comes from his lack of ego, his confidence in his abilities and his desire to educate others.
Also, you need to handle and shoot lots of rifles from different manufacturers to get a good idea of what's available, what's possible, what is outstanding and what is garbage. Media Day at the Shot Show is a great way to do this and you'll be surprised at how many firearms companies don't show up because they know that their garbage won't compare well to everything else on hand that's readily available to shoot. It's much easier to look good in a gun shop when you're being compared to other equally average products, and you don't get to use the firearm as intended. It's a much higher bar when there are fifty different manufactures on the firing line and you see feeding issues, bad triggers, heavy bolt lift, stocks that suck, etc.
