Add me to the list of those preferring a single-stage trigger. I use the JP trigger/hammer combo on my Bushy Shorty. Trigger pulls very much like the Timney triggers on my 700s. I don't like "takeup" in a trigger pull on a rifle. Trigger breaks @ around 3#, with no discernable creep or overtravel.
What combat soldiers prefer is largely irrelevant to the type of shooting that I do.
