I think some people have a natural ability to discern differences in quality better than others. Whether it's a gift of greater senses or an inherent or learned aptitude, I don't know. But, I have no doubt they have the ability to distinguish small variances in quality. I try to seek out their opinions when shopping. For my part, I can usually learn to appreciate the differences between a "C" level product and an "A" level, but it ends there. I simply cannot distinguish an "A-" from an "A+" in most things, be it wine, audio equipment or fly rods. Because of that limitation, I tend to shop for value which is cost divided by the quality rating I assign. I find I'm generally satisfied with the solid "B's" out there.

BTW, I totally agree with NJTroutbum on his evaluation of Orvis' 5 wt. Far-n-Fine!
