I have attended several tier one schools (Blackwater, Frontsight, blah blah) and Valhalla is by far the most progressive and realistic training available to civilians.
The only draw back is that AR work is limited. The ultra-realistic scenario-ranges can only sustain handgun frangible rounds, so you need a 9mm AR to be able to play (they have them for use on site, but then you are not using YOUR gun/optics, etc.). It is a great reason to build that 9mm carbine you always wanted!
Take the Extreme CQB course. It is the only place where you will be able to be in a bar, get in a fight, and see if you can draw and fire under serious duress. A Chicago cop buddy of mine took this course with me and said it was better than any LEO course he ever attended.
The real bonus is that the Elk Mtn. lodge is really deluxe with 5-star accommodations and dining. Makes for a great trip.
