Re: orvis float shooting head.
Cliff’s right … I strongly recommend you forget about using 6-weight head on a 3-weight rod. Neither the 3-weight nor the 4 are wind fighters; in fact, the 5-weight fares little better if Mr. Wind is up and about. With only rare exception, wind fighters begin at 6-weight and range upward to several relatively light 10-weights. Rods above this level a place in the blue water category.
One of the typical errors made by many fly fishers is not equipping themselves for the major adversary likely to be faced – on big waters and/or the salt, that adversary is most likely to be Mr. Wind and not Jaws, the Great White. I teach my students to select lines and rod weight designed to get the fly to the fish. Along the Texas coast, I recommend an 8-weight. That doesn’t mean that a lighter weight cannot be used, it can – provided the wind is on holiday. Several years ago I did a 3-part series entitled, “Revisiting the Shooter.” You might want to take a look.
For more distance and wind fighting, a shooter is the way to go. I haven’t thrown the latest Orvis heads but let me quickly add that the differences in lines between manufacturers is vastly diminished over what it was just a few years ago, What’s more important that who made the line is whether the line is formulated for the warm waters of the tropics or the cool waters of the north. Using the right head in the right water is important.
As Cliff said, efficient and effective use of a shooter requires the double-haul and the ability to toss tight loops. To that let me add the sidearm cast. The fact is the lower to the ground you can cast, the less the effect of the wind. The morale of the story is use the wind to your advantage: (1) if Mr. Wind is blowing from your rear, make a low backcast and a high forward cast; If he’s blowing head-on, make a high backcast and a very low forward cast under the wind.
If I can be of further help, just ask.
