Greetings all from sunny (er... not) England.
I notice that some rod makers are producing very expensive fibreglass fly rods. Now I completely understand and adore the bamboo rods, and I understand the benefits of a good carbon rod. I'm not so sure of boron (Winston!) over carbon but I'm willing to accept there may be benefits. Over here boron and kevlar did have a flurry of being used in high-end fishing rods but over the years it's died away to be replaced by higher and higher quality carbon.
What I don't understand so much is fibreglass. Pre-carbon of course fibreglass was king, but these days I can't see how it can be anywhere near worth the cost being asked of them. Diamondback for example do one at $300. That's not small money.
