Best way I've found :

Use a double jig rig to help distinguish your baits from surrounding "noise" or small fish, etc. You may also catch doubles on occasion.

Click your LS transducer back a click (or two) so you can see the baits "splash down" on the surface. (the only negative in doing that is that you lose distance "backwards" from the transducer)

That's not to say your ways won't work ... this is just how I do it.

The only negative on the split shot deal is it "may" make the jig fall too fast, and/or it may "lead" the jig (if it's heavier than the jig) and be the first thing the fish sees. The plastic threaded on the line sounds like it would work better, but keeping it in place on the line may be a problem.

Using braid is fine, but just make sure the rod & guides are capable of handling braid.
