I think you may be 'overanticipating' the amount of required pre-travel when using in a 2 stage on a rifle. It's not as drastic as in a pistol. Sure it moves a little more, but in terms of actual pull weight needed to a 'break' in a 2st vs 1st, the amounts are roughly the same. So in essence, if you're 'blipping' the trigger, you're using the same amount of force & finger motion in the end for either offering, but you may feel it just a tad 'bouncier' shooting in quick succession due to the slight travel involved.
Lots of folks use upgraded 2-stage triggers with good results in drills, training & competitions.
