The answer to your question is...It Depends...
In my mind it depends on what motivates the person to hunt in the first place. If your motivation is being successful every hunt, or only killing mature animals every year, then I think lots of "would be" converts never give it a try, or decide fairly quickly that it's not the correct weapon for them. I think more and more people fit into this category each year. It takes a special mindset to embrace being unsuccessful hunt after hunt.
The folks I see sticking with it are those who honestly don't feel the need to prove anything. They are ok with not killing a bull, or are willing to shoot a spike buck. They are ok with the proverbial tag stew and love the process as much as the photos for Instagram.
Let me tell a story to illustrate. I have a buddy that drew a non resident bighorn tag in Nevada last year. I helped him out and really early in the hunt he shot a young ram with his recurve. He was ecstatic! As was I. But you would never guess the number of locals around here that gave me a hard time about "letting" him shoot a young ram. They all lost sight of the hunt and the challenge associated with traditional equipment. They were too caught up in the trophy aspect of hunting. They are the types of hunters that will never try a traditional bow.
I want to be clear. There is nothing wrong with that mind set. It's just not the mind set that will work for becoming a traditional bow hunter.
That's my two cents.
