It is true in my experience that guides in general are not gun enthusiast. In some ways, that makes them more perceptive, as they simply care about what works, not what they want to work, or what they dreamed up in their head. Most guides I know do not do a lot of personal hunting, and may not own very many firearms, especially expensive, fancy ones. But they do get much experience seeing what works by sheer volume. Each client is a new rifle and a new lesson. When you do something for a living you note what tools work and what don't. There will still be differences of experience and opinion but you do notice trends. One of the most notable and universal is that those who brag a lot about their skill or equipment are rarely much good with it.
