re: Glass or composite cranking rods?

I’ve used both and I wouldn’t say it’s worth it for shallow running cranks. It’s really hard to describe the difference in feel, but I’d just call it different as opposed to better. I think nostalgia sells more glass rods than anything but it does give a little more consistently over the length of the blank to keep the fish hooked while still having backbone. It used to cost more in a graphite rod to achieve that but I don’t think it’s that hard to produce today. If you’re not losing fish currently, I wouldn’t fix what ain’t broke.
