OMG...I agree with everything you said, including the modified weaver. Is Obamas brainwashing emitter already in operation?Don't get yourself too caught up on "which stance do I use" versus which stance do I not use. That is all well and good for the range, but what stance you are using goes right out the window when something other than a piece of paper on a target stand rears its ugly head. Practice shooting with different stances and get comfortable shooting from otherwise uncomfortable positions/stances. If you are using cover correctly, seldom will any particular stance "win out" over another.
That being said, I often shoot using a modified weaver or some hybrid that resembles it...whatever works best to accurately put rounds on targets at any given time.
