I much prefer to catch smallmouth on single hook lures. It is easier to keep the hook tight and land the fish and you have no chance of hooking yourself.
The fluke I was using was actually a pink floating fluke from Strike King 3X ElazTech . I had a weighted hook to get the bait down in the zone. On the bottom, the tail would wiggle in current like a shakey worm. The bait doesn't sink well like a Superfluke, it's designed to float- BUT, the major breakthrough here is the ultra soft (squishy) plastic, that just refuses to tear! Eureka! The major factor to the detriment of most fluke baits is they often rip on a single or a few fish. Try as you might, the bait just won't run right after a piece of the head is torn. It often has to be rigged perfectly to get that 'glide' the bass love. Well the geniuses at Strike King have found a plastic that is hard to tear. I caught 15-20 fish on one. The fluke would slide over my snap and up the braid without tearing again and again. I thought something was wrong when I had difficulty getting the hook throught the head of the bait. The plastic is just that elastic.
Another nice thing about the Strike King Floating Fluke, if you crank it fast, the bait swims like a swimbait. Smallies have been loving a stop and go retreive lately. Flee it fast, drop it to get bit, repeat. Looks like a sinking version will have to get ordered for a test.
