Agree with the poster above, I always use braid when jigging eyes with spoons/raps. I usually use a mono/flouro when finessing perch/crappies. Seems a little tougher to get little jigs down quickly, but maybe I’m just imagining that.
I always use a couple of ft flouro joined directly to the braid. Best way to do it, in my opinion, for a few different reasons (less gaudy unnatural metal to turn off negatives, bangs up eyes, stronger connection, etc)
A big thing for me, slip bobber fishing doesn’t work so well with braid. If you want to slow down on some negatives, I like to always have a rod or two available that I could throw a slip bobber on that I can set to nearly negative buoyancy to elimate the floats resistance on the very tough biters. Sometimes, that, with the rod set down in a holder, is the only way to get a bite. The slightest tension in that offering will cause them to spit it. String stops don’t stick to braid and slide around on you. It’s possible to do it, but it’s a pain in the rear.
Long story short: it depends on what you’re going to do in terms of presentations/techniques. (And how deep you’re fishing. Not as much of a difference in stretch at 10 ft compared to 40 ft).
