a few things come to mind that are extremely important. first, an extremely consistent trigger. regardless of it's weight, creep, or any other unique characteristics, if it does the exact same thing every time you can learn to shoot it. i'm not suggesting that correct adjustment of a trigger isn't a good idea but consistency is important.
consistent pre-load is extremely important. especially with a hunter rifle.
a two stage trigger is a mechanical and, hopefully, consistent form of pre-load. with the 2lb trigger it is the pre-load that allows the unconscious shot. there is nothing unconscious about pulling thru two pounds of trigger without it.
you have to be mentally prepared to break the shot. it is very common to hear of folks that hold all day long inside the animal but just can't get the trigger to break. and then when they do finally break the shot it doesn't go where they had hoped. as Marv says, "you got to get your mind right." i get there with a breathing pattern. others get there by training to break the shot as soon as they see white. that works just as well if you have a good follow-thru.
