Mas is a great teacher and can really get the point across.
He helped me with a research paper on OIS Policy about twenty years ago. I finally broke down and attended L.F.I. 1 earlier this year. He is also a prolific writer that knows his subject material very well.
I may not agree with him on everything, but there's not much I disagree with him about. He understands human dynamics and is able to blend two diferent disciplines together seamlessly, shooting and the legal aspect of shooting. It's been said that teaching is an art form. Mas must have a Phd in the "art" of teaching.
IMO taking L.F.I. was the best gun "investment" I ever made, and I regret not making it sooner. If my choice is an LFI class or a $1,500 gun, give me the class. I'll buy a $300 gun and be better off.
