I started with braid fishing for grouper tightlininng a Carolina rig down around 100' deep. We put mono on one rod and braid on the other. We caught 10 to 1 over mono because of the stretch over those depths affect sensitivity and you miss fish when you do not feel them. On crappie, I am convinced you will feel more with braid especially when your tightlining down deep, but getting hung without a leader that will break away is a real problem.
