Another technique to consider for trout streaming, is to cast out 70-50 degrees ( this can vary depending on what cast you are using. eg. a double spey throws your line a little more up stream and a snap t a little more downstream ). When the line is at 45 degrees, begin stripping it in. I find this extra action on the flies works well on trout. Take some steps downstream and repeat. This works very well for me on the bow. Swinging fles is great for steel, not as productive for trout. Good luck, and welcome to the spey cult.
