I like and use circle hooks sometimes for streamers and buggers. I found out that you don't really set a circle hook you more or less smug it. When I feel a bite or resistance I slowly ease all slack out of the line and the hook sets itself in the corner of the mouth, they were designed to do that. I started using them several years ago when I was bait fishing for Cats using several (4 to 5) rods at a time, all I had to do was bait the hooks and sling them out and wait for the Cats to hook themselfs.
