Without a doubt frogs are a great selection. However, as most of you realize, especially in tourney situations, you often need to show mr. Bass something different. Two things I've used are a chug bug and/or a chatter bait. Cast the chug bug past the patch of pads and slowly drag it through. Most of the time you can bring it through without getting hung up.......slooooow is the key. If there is a pocket in the pads, give it a twitch and hold on. With the chatter bait, slow roll it through the pads. It actually comes through better than a spinnerbaits and works especially well on cloudy days.
A frog is nothing more then a top water bait. I have found that there are days when every bass in the lake are hitting top water. You can't keep them off it if you tried. I have found, much more frequently that the fish are "inbetween" They want it but not really. The hits are half hearted at best. If I am on the water and fishing frogs or any other top water and I encounter situation #2, I give up on topwater pretty quickly ( after 3-4 half hearted attempts by different fish) and go with a sub surface type bait. It's more frustraiting to me to get half hearted hit and not hook up then to get no hits at all.
