I don't use swivels on any leaders at all. I have had perch pecking at my swivels years ago and if perch can see them so can muskies. How many time have you heard of guys fishing with little jigs and catching muskies? They see small stuff just as much as they see the little things.

If you use a flourocarbon leader cut off the swivel just above the ring that attaches to the flouro. In other words leave the bottom ring of your ball bearing swivel to attach your line to. If you direct tie your line to the flourocarbon it will in time cut through the flourocarbon. That's why you leave the little metal ring on the leader.

For the Chippewa Flowage where the water is stained, a single strand wire leader is just fine. On this you don't even need the little metal ring of the swivel. Just direct tie right to the wire.

Here is the trick for your bucktails if they spin. Take and bend the wire of the bucktail just below the eye where you connect your leader snap. Bend it at a 45 degree angle. That will eliminate any line twist from bucktails rotations. It will make the bucktail run true.
