Perch are very picky eaters. They are like salmon in a sense. They like it warm with no sun. So if its a warm outside and sunny, look for a place in the shade and cast your comet about 2 feet outwards form the sun to shade line. Also try blue fox spinners, they also work great! Good Luck...
Trout are tricky. Cant be too warm or too cold. Try to fish with and overcast. Then use a BlueFox Lure, Gold, Blue or Silver and cast away. If your a more lazy style of fisherman, try the basic worm hook and bobber. Works just as well. (Size 5-8 hooks)
