No need for a leader to the plug. Since a tuned plug does not spin. Use a mainline that is 12-15 test. The lighter the line the less the push from the current on the line resulting in deeper diving plugs.
VERY IMPORTANT ....tune the plug so it dives straight down under pressure.
You will improve your hook up ratio if you replace the cheap hooks with a larger hook. You should also extend the hook farther back on the plug by adding a swivel or a long split ring. This will get the plug away from the hook for a better point exposure. Make sure they are razor sharp.
In clear water Black is king of the colors. Take your gold colored plugs and dip the bill in black paint.
Distance below the boat for line length is based on the depth of the water your fishing or distance to brush piles.
Plugs are normally run in tandem. You may spook one fish into biting the other plug. Run your plugs equal distances below the boat. You can add markers on your line or use the same type of reels and count line passes on the reel.
You can also experience short strikes on the plugs. Patience will get that fish if you keep plugging the hole the fish usually hits again. Wait for the rod to dive.
Truly the hardest part of plugging is the art of rowing them properly through a hole.
Would love to hear some of your ultra clear techniques for brats. They would work great in some of my extreme low water fishing.
