Just to reiterate, back in 'Dr. Hudson's Time' (early 1900's), the term "drag" meant the first-stage of the two-stage trigger. It was new to shooter's. They didn't like it and got away with eliminating it from their competition Krags.

If you like two-stage triggers, (I do), they serve the shooter well and are required by match rules.

IMHO - A good two-stage trigger has lots of sear-engagement and allows you to smoothly and predictably take up the first-stage and come to a distinct 'Stop'.
The second-stage crisply releases with 3 to 3 1/2 pounds of additional pressure.

The problems to solve in a two-stage trigger are 'creep' (grittiness, roughness and friction in movement) and a heavy release of the second-stage.
Personally, I have never been bothered by 'over travel' on a rifle trigger.
