Like Indianahunter said I have never fished a frog any other way than on top. However, I actually like the soft plastics frog baits better than the scum frog or the spro frogs. Here are a few of my favorites. I will give you one piece of advice. If you useanyof the soft plasticfrogs make sure you buy the frog hooks that screw into the head of the frog. They increase the life of the frogs trememdously. Before I tried the frog hooks I was only catching one fish per frog and it would be tore up and I would have to replace it. With the frog hooks you can catch 3 or 4 fish per frog.
Mans Hardnose swim toad: Green pumpkin/chartreuse is my favorite color.
