Mike put you on the right path, the common cents system is a viable working
system that the rodbuilders here in the US have used for two years now.
Japan and europe really have run with it to the point that some manufactures
are talking of using it on the rods. Sounds like they have come up with two
ideas, some will put it with the rest of the info on the butt section of the
blank forward of the grip, but most seem to think they want to put the
action angle and power on/in the butt cap. Seen some done that way, really
sets the rod off and it's right there where you can see it when you open the
bag on a multi rod transport into the bush.
