Stuart--I would LOVE to take more classes from some of the great shooters of our time. So far for me, Bruce Gray and Jerry Jones at one three day class, and Brian Zins and Andy Moody for a two day bullseye class. Each taught details and trigger control. Learn to pull the trigger without moving the gun.
I know a lot more about shooting a pistol accurately than I can put in to practice, that's for sure.
Glad you got to go, sounds like a perfect (training) group size and I bet what you learned will keep you busy for years to come.
Joe
