No, a rod is not a rod is not a rod. In fact, quite the opposite. There are a few good sticks that make casting fun and graceful. There are a lot of poorly designed products that are barely worth calling fishing rods - I relegate them to the category of "poles". That said, price has almost nothing to do with the action, castability, inherent accuracy or utility of rod. A good taper, proper guide spacing, and efficient matching of line-to-rod-to-casting conditions is the sum total of the physical equation.
My point is only that, all things being equal, you won't catch more fish with a $1000 Russ Peak than you will with a $100 Fenwick or a $3000 Leonard or a $600 Sage. If the tool is properly designed and used, the only thing the additional investment buys you is art.
I'm not denegrating that pride of ownership. Quite the contrary. I collect, I enjoy and I daydream about the 'big stuff'. I hope to have the money to own it all one day
