Anyone that tells you that they have THE way and nobody else knows what they are talking about...is full of it!
Put another way, competition shooters will use whatever technique they need to use to win, ego is wrapped up in results not how they look...well, except maybe for Mike A., lol...if this worked as well as professed, you'd see it all over the range.
Consider also that top Military and Police units are going to top USPSA/IPSC shooters like Rob Leatham, Todd Jarrett, Jerry Barnhart, Ron Avery etc. for training should tell you something about what they feel works...
