The set trigger is a very nice additive. Especially on the range. And believe this or not, since most my shots are taken at unaware animals, I use the set trigger in the field. A word of warning.. take your gloves off when you want to shoot in the field. A fat gloved finger and the excitement of the moment can lead to a too quick of a shot.
Although there is nothing wrong with a good single trigger rifle. Many of my rifles have excellent single triggers.
