it is interesting to me that they offer a "part " of the rod for sale as a replacement , this indicates one of several possibilities you know .
mass produced and not so perfectly balanced would be my first thought and then expectations that it will break is my second thought .
now mind you never had one in my hand , but I do know some of the best rods around you cant buy a top half alone for them .
very interesting to be sure and has my gears turning , wonder if Loomis or St. Croix sells rod halves/replacement uppers too ?
we should explore this further no doubt about it ....
so is JDM a brand or does it just cover any Japanese sold rod ,somehow i am lost on this subject totally
