I can't quite agree with Sam Vimes on new rings on old rods, I'm a bit of a barbarian, and if one of my bamboo "users" needs rings replacing, it gets modern ones, and is usually vastly improved by it. The longer and less ledgery it is, the greater the improvement, the prime example being my 12' reed ferruleless (i.e. cane-to cane joints) Spanish reed job, which has been completely transformed from something Geoff Capes might have trained with into a magic wand even I can wield for ages. Trots way better, too.
Once I've shuffled off and all my kit's been ebayed, the next owner can fit High Bell's "Life" rings if he wants, but if he means to fish it, I can't see them staying on for long.
