I agree with LSP552. We were typing at the same time apparently.
Not to dog pile, but remember, the goal of all of this at the end of the day is to have your skills at as much of a pre-conscious level as possible. I think this is true from a defensive standpoint, a competitive shooting standpoint, and everything in between, frankly. I'd personally have concerns over having multiple trigger finger positions. But perhaps even more so, I'd have concerns having to change your grip going from one to the other.
The DA/SA analogy is a good one. I find that there sometimes needs to be a compromise for some shooters between where they best press the DA and where they best press the SA. The concept of repositioning the finger in between shots doesn't hold water, IMO. And I feel the same way about the prospect of having to re-adjust one's grip to shoot one-handed.
And your pixels read just fine, btw.
