2 stage triggers are a unnatural feel for me, if used on anything other than a scoped rifle when you have time to take your shot.
whenever i've used them on rifles with iron or RDS's, i find that trigger manipulation gets wonky if you are going to speed or double taps. just too old for new tricks i guess.
for scoped rifles, its the only way to go.
i know the timney guys all seem to really like their triggers but if timney is still using that set screw to adjust the disconnector, i would pass. the set screw on my single stage would walk out and prevent it from letting go of the hammer on rest. although i think i am the only one that ever happened to. haha...but for me, its to much of a variable in a rifle i might use to defend myself. on a range gun, no problem.
