There are so many ways to fish these types of frogs, the best way to sum it up is to vary your retrieve. Vary it from cast to cast or vary it within the cast. You can not fish them too slow or too fast, let the fish tell you what they want. I primarily fish them in the thickest cover, but have also had fish hit them in completely open water as well.
A tip that sounds pretty obvious, but a lot of people disregard, watch reel frogs. Pay attention to how they move through the lillies and what not. Something I have picked up on is that real frogs rarely pause too long in open water. With that being said, when there are patches of open water within the cover I will fish slower over the cover and speed the retrieve up when I hit the open pockets. Of course this is not the one rule to stick by, because I have had many hits in the open water on a long pause.
Real frogs also sit in one spot for an extremely long time, so if you have the paitience, there is no lenght of time that is too long to let a frog sit in one spot. I am talking 5+ minutes, I do not have the patience for this anymore, but I once did. I figured this technique out by getting backlashes on my casts and taking a long time to dig them out. As soon as I moved the frog BAM fish
Good luck and as said before, be sure you feel the fish before you set the hook. The bronzeye frog is an excellent frog to use, good luck with it, and let us know how you make out.
