I believe that a more expensive arrow could very well have an affect on your ability to make a better shot, which in turn could make you a better bowhunter, to an extent. You're only as good as YOU are. Buying good quality products helps to make you a better shot, of this I'm sure. I'm not saying to go out and buy the most expensive arrow on the market but buy what you shoot the best. I think why you asked the question to begin with was for the same reason many threads get started on here, to get numerous opinions and try to avoid the trial and error method that people have experienced before. That's the best thing about this site, members will always help you the most that they can. Good luck in finding that perfect arrow for you and if it makes any difference I shoot the Easton Axis arrows TOO and they hit like a sledgehammer. They shoot great, penetrate like crazy, and you can get them in 2 days from any big outdoor store like Cabelas, Gander Mountain,Bass Pro or the like, just not Wal Mart.
Well said sir.
Archery like many things in life embodies the old saying: "You get what you pay for."
