I agree with you where you say rods today are much more fragile than they were a few years ago.
The rod I use for all of my fishing, be it still water for trout or sea trout fishing is the same one I've used for 23 years!
When I was 15 years of age I was fortunate to qualify for the Welsh youth team. For my efforts my father bought me a Fibertube carbon blank (it was cutting edge 23 years ago), that rod is still going strong and I love it as much as anyone can love an inanimate object. Sure it needs a little TLC (it's going for a little R+R at Foxon's this winter).
About 6 years ago I bought a Sage 9'6" which was killed in a blue on blue incident with a car door. I'd only had it for 6 months, and because I'd bought it second hand I couldn't claim on its lifetime warranty. So out came the Fibertube once again, same fuji eyes as originally fitted, and it's still going strong.
That said, I don't half get some strange looks of other fishermen when they see the rather battered finish, the insulation tape I have to put on the ferrule to stop the top section making a dash for the horizon half an hour after I start fishing, but hey, it just adds to its character.
