#1 Rule: Make sure the weapon is pointed at the intended target!!!
I also tend to pull straight through to fire. Too used to SA. Given the choice, I shoot all my DA/SA in single action with slower aimed fire. As I cock on the draw, this is no problem. On follow-up shots, I figure I have to go fast enough I won't have to stage the shot. I did have a DAO GP-100 spurless and could not get used to it. If I ever get the Taurus Protector, I may practice more with this style. My Trackers both are fairly easy to stage, but I seldom bother, as it takes me about as long to stage the hammer as to cock it. Biggest advantage with DA and stageing is the gun stays on target a little better.
I don't try staging with my M85 too often. Not much call for it in the arena if it's intended use. I do, however, greatly enjoy the practice with my M607. This does not mean I don't shoot it SA it as well. Thumbing back the hammer on any type of forearm is one of life's great pleasures.
