Re: new to saltwater
Just as with freshwater fishing, saltwater covers a lot of ground. Much will depend on the area, & what species of fish will be present at the time, and the weather conditions. For example the same rods & flies used for big Tarpon will not be the same as might be used for much smaller species, even smaller "baby" Tarpon. Generally, most folks begin saltwater fishing with at least an 8 wt, and baitfish patterns, such as Lefty's Deceivers can fit a wide range of species & situations. The sizes will also vary widely, again depending on conditions & species.
If you can get a bit more specific information about what species you may encounter at that time of year, it will be easier to give recommendations.
