However, like all generalities, there are exceptions. Tarpon come readily to mind. Flies used for tarpon aren't too large and, in fact, have gotten smaller over the years. Instead of the 5/0 and 4/0 hooks that were once typical, today use of 2/0, 1/0 or even smaller hooks is not unusual, even for big fish. And with the exception of dirty-water situations, where flies are tied bulky to "push" water, tarpon patterns have always been relatively sleek flies. A 9-weight rod would cast these easily, but a 9-weight is no match for a big tarpon. Stout 11-, 12- and even 13-weight rods are better suited to "putting the wood" to 100-plus-pound tarpon.
