It just depends on the sunfish really. Most of the time they are in the right mood and you can pull in bucket loads, even if they are 2 feet in front of you and staring you in the face. Every once in a while though there are times when you have to be ultra stealthy with mega-bionic-invisible-ninja fishing skills (yes, I did type that) just to get one bite an hour. Its not often that happens but it can be very frustrating when it does. Like mentioned above, fish the first deeper break and you should find some decent bulls.
