These Panther Martin Fly Spinners are also known as "Uncle Martins," I believe, and are a must have in every color if you're fishing trout or salmon. They're a bit heavy, which provides for a nice cast, and also have a good blade angle. These two factors together means that they run deep, which is good for trout fishing. I like to use a 1/16 ounce, silver one with the yellow body since I usually an looking for trout in the mountain cricks. As usual with trout spinners, fish upstream. Some more popular colors can be seen in image 2. Additionally, you can do a steady fast retrieve, or you can do a tip shake as seen in this video on slide #3, which teaches the basics of fishing a Panther Martin Spinner.
