I know that rod technology has changed a lot in the last 20 years. So much has been done to increase sensitivity and make the rod lighter. However, when you are looking at comparable, higher end rods (older GLoomis GLX vs. new GLoomis GLX or older St. Croix Legend vs. new St. Croix Legend), how much discernible difference do you think there is in sensitivity? Is an older GLX going to have comparable sensitivity to a new IMX rod? Or would an older GLX still be comparable in sensitivity to a new GLX?
