The other option is to "punch" the pads: Stick as big a bullet weight on there as you need to crack through the pads, and rig a slender-ish soft plastic bait on there. Brush hogs, beaver-style creatures, things like that. Put it on your favorite frog rod and fish it on braid or heavy fluoro, so you stand a chance of getting the fish out again.
You want to try and aim for small holes or seams between the pads, both because you can then get through and because the fish tend to congregate around those things. If there's other structure mixed with the pads, like a log or a stump, try around those too.
When you get through the mat, you have three "phases": On the fall, where you will get hit most of the time; Once on the bottom, give the lure a bit of action and see if it got followed down. If you have not yet gotten bit, bring it up until you feel the pad mat, then jig it around just under there. Retrieve and repeat.
Getting bit will most often just feel like there's extra weight on the line. Whenever you feel something out of the ordinary, swing for the fences. Hooksets are free, after all =) Most of the time, the pads will ensure that you do not nail yourself with your 1oz weight, but it never hurts to assume the worst! Getting beaned with a 1oz lead sinker is not a good time.
Once you have a fish on, you need to lay on him as hard as you can to get him up and out of the pads. This is where heavy line, a stout rod, and heavy-gauge hooks come in. If you let the fish muck around under the pads too much, you will lose it most of the time.
You can also combine the two: Fish a frog over the pads to locate fish. Once you get a blowup but the fish misses, follow it up once more with the frog. If it's still no good, drop your punching lure through and give the fish a different option. You know it's there and it's active, at least.
