Twelve Weight Fly Rod
I like this for tarpon fishing because it easily cast the huge flies and has the backbone to handle the largest fish. It is also good for the large king salmon, large tuna and wahoo.
Thirteen, fourteen and fifteen weight fly rods
Here you enter into the blue water arena and are specific to the species and, more importantly, the methods used to catch the fish you are targeting. For example, many of these fish are targeted in deep water (>50 ft.) which requires very heavy sinking lines while others are teased to the surface which may only require an intermediate fly line.
Don't forget to have fun while you're out there!
As I am sure you have noticed, I make no reference to the action of these fly rods. The way a specific action works or does not work is purely a matter of personal style. Some prefer faster (stiffer) actions while others prefer a medium or even slow (soft) action as in the case of many glass and bamboo fly rods. I recommend to anyone seriously considering the purchase of a fly rod; go to your local fly shop and cast every rod you can get your hands on. Don’t worry about which action your lifelong friend prefers or which action your favorite guide likes, this is purely a matter of personal preference! Another recommendation I feel is worth it’s weight in gold is to buy a new rod with a lifetime warranty! There are many to choose from…..
