nyeti and Wayne, you know I love you guys but I'm throwing the flag on the "until you've been there" play.
All of the instructors at Rogers are experienced LE and/or military guys. They've all worked at night. They prefer the Rogers technique.
All of the Surefire Institute stuff (much of which formed the genesis of the Strategos program) came from experienced military and LE guys, too. And they don't agree with the guys at Rogers, who don't agree with what you're saying.
I could go on and on. Clearly, reasonable experienced people who've studied this stuff at length have come to different conclusions. It would be stupid to ignore what you guys have learned and concluded from your experience. But it would also be stupid to ignore what those other guys have learned and concluded from theirs.
Getting more specific, i know from experience that I can shoot better SHO/temple index than from a Harries. I can maintain the temple index with absolutely no fatigue, and it's very easy to make it work with L and R barricades without changing my grip or having to move the light much at all. It gives me completely independence between where the light is pointed and where the gun is pointed. I'm genuinely curious what you find in Harries (and I'm unfamiliar with "reverse Harries") that you feel has an advantage over that. I'm happy with play with it again -- I haven't shot Harries in years other than a few shots here and there while teaching -- if there's a legitimate benefit.
