Hey Billy,
I use 2kg mono with no leader although I usually tie a double.
Although sometimes bream will smash a SP usually they will just pick it up very softly and mouth the lure.
The only indication you get is the slack being drawn out of your line.
Treat the fish like you are bait fishing when you feel this and drop your rod tip allowing the fish to move off with the lure.
When the line tightens up just lift your tip without striking and 9/10 you will get a hookup.
Takes a little while to get the technique right but once you get used to the way bream bite you will have better success.
Also it's much easier when there's no wind to feel what's going on.
Good luck,
Rod.
