It depends on a number of factors imo... Can you do a roll cast? Do you want to cast well or just fish? Do you have time to teach yourself? Do you have time to practice a lot? Do you have friends that can help you? I think the biggest factors are time, and desire and focus if you want to teach yourself. I think casting is pretty strait forward and easy with modern lines, if you just want to fish. And if you can figure out the modern lines. There are many guys happily fishing along with good success who could benefit from some feedback for sure. Also, there are many really bad casters on a busy day on the river. I rarely see anybody who can cast very good at all.
