The water that I fish is gin clear and is filled with rocks and zebra mussels, and I don't find that braid does well when I'm fishing around such structure. As well, it helps from straightening out small trebles found on a lot of jerkbaits and also pulling said lure away from fish too quickly, something which in the past has cost me a few decent sized fish. Finally, braid is so limp that I would get line around my rod tip and into my trebles on practically every cast. That, to me, is a pain in the backside.
Since incorporating a fluorocarbon leader, I haven't lost fish in any situation noted above. As well, I haven't noticed any adverse impact on the suspension, rising, or sinking characteristics of the jerkbaits that I throw which include Rapala Shadow Rap's and Shadow Rap Shads, Strike King KVD 2 hook baits, and Lucky Craft Slender Pointer and regular Pointer family baits.
Hope this helps.
