Mickie,

Nope, that's not a fly. It's a spinner. 1/4 ounce is a bit much for even a 9 weight fly rod to fling.

However, you can tie some flies with spinners on them that do cast well with light fly rods. These were VERY popular historically with fly fishermen, and many old books and catalogs show these flies.

Smaller blades, 0s and 1s, plus the ever popular 'propellar' style, readily lend themselves to flies.

I stay away from using a clevis (that little 'U' shaped piee of metal that the blade rides on as it spins around the shaft of the 'spinner') as they seem to both twist the tippet badly and make tangles worthy of photographing....

Hooking a small indiana, willow leaf, or colorado blade to a small roller swivel, either at the head or tail of a fly, does work well, though. The 'propellar' styles are even easier, just slide them onto the hook behind the eye.

Adds flash, vibration, causes interesting vortexes is the water that make materials act more alive, etc..

Good Luck!

Buddy
