I was in Keith's H1 class, and it was incredibly valuable. I've taken classes from a number of top name instructors, and only Steve Anderson gave me the level of detailed, personalized training that Keith Tyler did. I've been at the top edge of B class in Production for a year, and Keith helped me understand what's been holding me back. I now have a short list of things to work on--all actually quite simple, but that I would not have figured out on my own.
For the cost of ammo from three practice sessions, Keith Tyler's classes are a serious deal.
