if you're after popping i believe you have the wrong set up.
the 20000 stella have a low gear ratio.making that reel the ideal reel for jigging and not popping.you have to go with high gear ratio,sw 10000hg,or sw8000 hg.
or you might want to consider the daiwa dogfight or the daiwa 6000 GT.
anyway if you have to use it,your best set up will be,
tie a PR knot, braid to shock leader,make sure your shock leader is rapped up 2 turn on the spool,this way when you cast your finger tip is on the mono leader.then at the end of the shock leader tie a solid ring,out of the solid ring
connect a split ring.and have a split ring plier handy to change lure.
that is you ticket to land a big fish.
good luck
