Take it now. Better yet, take MAG-20R and MDFI classes. I had not heard of MDFI, but if Pat Rogers says it is good, believe it.
My wife and I attended MAG-20 back when it was Judicious Use of Lethal Force (or something like that), the classroom portion of LFI-1. Mas is a superb instructor. Some day I hope to take MAG-40 and more training from MAG, and it sure would be great to have Mas doing the teaching.
However, if you really could find no training in 2 years that your schedule permits you to take, you might want to ask yourself why you want training. Do you want to get your copy of In the Gravest Extreme inscribed so everyone knows you are a close personal friend of Mas, or do you want training to help you protect your family? Cause Mas ain't going to be there if some dirtbag decides that you, your wife, and 3 kids are food some night while leaving the soccer field parking lot. It will be up to you, your wife, and oh yeah, YOU.
If you really repsect Mas, try respecting his choice of certified instructors.
As I said, I would like to take more classes with Mas. In the meantime I have taken a class with Steve McDaniel at Alaska Tactical and am signed up for a Louis Awerbuck shotgun class this summer. Long term I hope to take classes at Firearms Academy of Seattle (a MAG training partner), ICE Training, Thunder Ranch, Gunsite, Shootrite, PSA, Martial Blade Concepts, etc., etc. Good training now (from anyone) beats no training until it's too late.
