What the heck is it with recommending lines for rods and overlining them. It seems to defeat the purpose of what that rod was/is designed for. Overlining a rod dampens the action and instead of going a line weight or two heavier wouldn't just casting with a longer fly line work the same but with longer distance?? Seems to me that overlining or underlining a rod would make every rod cast the same distance and also feel closely alike. It's a simple function of a certain grain weight of line that is optimum for a certain modulus of rod.
