For BR and Whig, I too like the 2 stage pull. On my 222 Savage it has that new fangled trigger with the safety blade in the center of the trigger. Take the slack out and the next little bit of motion sets it off. Reminiscent of the military 2 stage.
If any want to take a good photo of the trigger on the action and compare to my shop made trigger, it would be nice to compare them to see if the desirable features could be easily had by modifying a standard trigger. Maybe Parashooter's trick plus modifying the "A" cam. May or may not be legal for your sanctioned shoots.
