I have caught bass on a little cleo spoon when I could not get anything else to work.

Try some red and black Zoom Speed Craws rigged weedless. The smaller craw catches me lots of bass, when bass are hitting slow. Work em fast as a topwater, slow or with a pull pause pull pause as a real frog would do.

If the bass are hitting the frogs but not getting caught you're setting the hook too fast. Wait til you feel weight on the line, then set it. Its tough to wait when you see the splash but you'll catch em if you just wait a few seconds.

Kentons right you are setting the hook to early. You can also try using a double hook like what Stanley baits make. Also what frogs are you using??
