Braid:
The Pros
Quality braid line will not stretch like mono so bites are easier to detect, The strength of braid line also makes it a great opposing agent to abrasion which causes other fishing lines (mono) to break. Fish often inhabit rocky ground or structure so your line will often come into contact with this structure so abrasion resistance is an important thing to consider when using braid.
The Cons
As braid has no stretch, it is much easier for the angler to rip the hooks out of the fish’s mouth. Any force imparted on the rod tip is replicated at the hook so take care when striking fish. Braid is also easier to see in water so most people will not tie a hook directly to braid, but rather attach a monofilament leader.
Although braid resists abrasions more than mono it does wear quite easily so any fracture or nick in the line should not be overlooked. Braid is also more expensive than mono unless you buy the chinese braid but expect a couple of weeks for it to arrive if you buy from there
