I just saw the tail-end of the pre-carbon rods. When I started fishing, the older kids who let me tag along to the canal had glass rods. The two kids who took it most seriously had Mordex and Milbro rods. They all seemed to have an old cane rod or two in the shed, hand-me-downs from dads or grandads who'd mostly given it up. I used to be allowed to borrow one of these, and I caught my first few fish with a bit of line tied to the end of a 9' cane rod. One lad had a posh cane rod, a very different beast to the shed remnants. It was surprisingly light and had a springy, unexpectedly "live" feel if you waggled it. Maybe that feel is what the retro dudes rave about? I don't know, as that was the last time I held a cane rod.
I had a few glass rods over the next years: a Sealey Blue Match (lovely soft tip), a B+W CTM 12' ( respected make but horrible action), a Shakespeare International (came with a cracked joint, so I claimed a refund) and, my favourite in glass, a Shakespeare Sigma Canal which I used so much I re-ringed it twice. I also had a couple of leger rods made by the East Anglian Rod Co - they were fine, and no big issue with weight at 9' or 10'.
The first carbon rods I met were a revelation. But they were pricey, and cost £100+ in the early 80's. They were by no means all great - the first one I splashed out on - a handsome B+W jet-black creation - proved too stiff and powerful for any of the fishing I did, and I swapped it for a Sundridge Kevin Ashurst, much better for light lines. The step-change from glass to carbon was huge, and even thought the weights have been shaved down and designs improved, there haven't been any comparable new developments.
