Just how do the manufacturers of rods decide on the ratings of their rods? I've only been into fishing now for a few months. As with so many other hobbies their seems to be gaps between brands with respect to certain criteria. I have a feeling this is no accident. Why is it that two rods could have the same power ratings, action,number of guides, and line weight, yet recomend different lure weights? The combinations change from brand to brand and even within brands depending on the line within the brand. So how do they decide if its a heavy, a med/heavy, etc, a fast, med/fast action and how heavy the lure you can use etc.? Why does there seem to be such a difference in opinions between manufacturers?
