This might not sound like it relates at first, but it does.
I took some acting classes a few years back and the instructor said I needed these certain books. These books are all I would need for acting.
Ok so I bought those books
I took another course and the instructor said Oh these are the books you'll ever need for acting.
So I bought a few more books.
I've read them all. They all pretty much say the same thing.
Do all these books pretty much say the same thing? I don't want to have more books in my shelf that are just going to collect dust. I want one that I can constantly refer back to once I've gotten more advanced. Which one is the most useful for an absolute beginner, that explains fundamental fly fishing language but still provides answers for more advanced?
