I've been on the BR forum for about a year now, and one thing I see over and over is the similarity in attitude toward fishing equipment and golf equipment. Each year club and ball manufacturers market the new lines as being exponentially superior to last year's versions, yet strangely enough, the the actual real world data shows that the changes in performance, if any, are minuscule. Most players can't perceive any change at all, but they won't admit that they bought the hype. They have to believe that the new gear has made them better, even though their scoring doesn't reflect that belief. I finally quit buying the orange juice about a decade ago.
I'm not good enough to make the same blanket statement about fishing rods, but it's hard to see how they can make any truly dramatic improvement, aside from bringing the price of the good stuff down to the point where I can justify trying it.
