I use a slip sinker on the main line ... which has a duo-lock snap tied on the end. And there's a bead between the sinker & snap, which has a hole large enough to slip over the knot. This protects the knot from damage by sinker movement or pressure. My baits are rigged on varying lengths of lighter pound test mono leaders, which have the bait on one end and a loop knot on the other. But, I'm mostly using jigs, not cranks.
The crank guys I know of are putting swivels on the end of their main line ... they pre-rig trolling weights on a leader and put snaps or swivels on the other end, then wrap them around a section of "pool noodle". Their cranks are kept in tackle boxes, arranged by color & model size. Their leader lines are generally 5ft long, and of a lighter pound test than the main line. Those that use "slip sinker" style weights are rigging them like I do my jigs.
Most 'bobber stops' are not sufficient to hold the heavy slip sinker weights in place, and if you use the trolling weights (which have rings &/or ring/swivel built in) the bobber stop would be redundant.
