I use PowerPro Braid 6lbdia, 20lb test for both pannies and bass/etc. I use a leader of 6lb mono for the bass and 4lb for the pannies. The braid has very little stretch and because of that is supersensitive and quick on the hookset. The mono leader has some stretch when it is needed ; hookset, hard pulls close to the hole by bigger fish etc. The drag and the rod do most of the work when a fish runs. Works for me. The braid does light my Vex up till it absorbs water, and then things are all good.
