Can't say anything about the Volquartsen, the Kidd 2 stage is in my ultimate and it's GREAT, I had it factory set at 14 ounces for the first stage and 7 ounces for the second stage. Great trigger I find for target shooting, I shot a sub 1/4" 5 shot group at 100 yds a few weeks ago with the rifle that has the Kidd trigger.
