I have a bunch of rods from a lot of different makers, I am not a brand fanatic. When I need a new rod to match with a new reel for a particular purpose, I try to find a match that works well for me physically because I'm tall with long arms. Usually the rods are rated for a range that is easy to understand, like "15 to 40" or "20 to 50" and it is pretty easy to understand how it will work, along with the ratings like "Medium" and "Heavy" and even "Extra Heavy." In the past, the rod that I bought with the widest range was an all-roller Kencor rated "40-100" that I use for trolling or dropping heavy lures for big tuna. But I have noticed that my new Shimano rod to match with my heavy Spheros 20000 spinner, a Terez TZS722XH, is rated "65-200" which is an insanely wide range. I'm using 80 lb. braid on the Spheros and wanted a very strong rod that I could fight big tuna with, and am confident that it will be equal to the task. But can anyone explain the reasoning behind a range of "65 -200" in a spinning rod?
