@Jig Man Those look good!
I've found the best places to fish them is in areas that are 4 feet deep or less and with submerged grass that stops growing within just a few inches of the surface.
Scattered lily pads also work well, where they can be fished in the holes and pockets between pads.
They do not, however, work well in heavy pads.

In heavy pads they tend to get hung up on the pads and will tear up easily. You could probably try lubing them up with some kind of oily fish attractant or worm oil, which would make them slide more easily over the pads, but it's easier just to use a hollow body frog in that kind of cover.

Pad edges are also a good area for these. I remember a night tourney where I found a 150 foot long stretch of pads along the shore. The pads only extended out from shore about 6 feet or so. I tossed the frog onto the pads and then worked it out to the edge. I had a massive blowup when the frog got to the edge, but it missed. So I tossed back up there and tried again. But this time when I got to the edge, I slid it off the edge into open water and then killed it right there. As it began to sink ultra slow, a big bass inhaled it.
I did this for the next 10 minutes or so and landed two 5 lbers., a 2 1/2 lber. and missed another one equally as big as the first two hawgs.
So be prepared to have some fun once you figure out how and where to use them
