For the OP question, you choose braid over mono because for the same diameter, it is 4-5 times stronger than mono, so you can put 3-4 times as much braid on the same spool as mono. Or for the same capacity, you can make it elephant-proof (why most people choose it).
I've never gone there either, and have visions of my buddy's 40-lb braid twisting up on his spinning reel during our coast trip last fall.
I'm totally happy inshore fishing with 12-15-lb mono. Also not too shy to fish 4-lb and 10-lb copolymer lines on the right rods. I prefer copolymer lines because they give you a little more toughness (knot strength) and abrasion resistance than high-strength nylon or fluorocarbon. They also have correct neutral density - monofilament nylon floats, fluorocarbon sinks.
But the good copolymer costs a lot - Seaguar, Yozuri, and a brand from Australia, Kamikaze (my 4-lb salt XUL).
Another reason to use fluorocarbon or copolymer is both lines become invisible in the water.
I tried some cheap 10-lb copolymer (Berkley) and it ended our day catching fish at Marker 60 pass, when the necking/stretching line slid inside the spool wraps and locked up my daughter's reel. Big sheepshead did that. It was OK enough, we had a stringer of schoolie specs and had been a successful morning. But of course never bought that line again.
Berkley still makes good monofilament nylon.
Seaguar makes good everything, and is still the first choice for fluorocarbon. 12-lb Red line as bing mentioned.
Nylon or fluorocarbon monofilament are offered in bulk spools (1000 yds) and it's smart to buy them that way.
There can be a few reasons that cause you to respool a reel on a fishing trip, especially a coast trip.
Last fall, had to re-spool a spinning reel I loaned to a buddy, and my baitcaster bird-nested when it fell of the rod in a cast (had a spooled spare reel ready to go).
Copolymer lines, we can probably only afford in a single-reel-charge pack, and as far as I know, that's the only way they're offered.
This is my salt XUL, which I use for dock-fishing at night. Made to throw 5g, protect 2-lb test, and a strong enough butt to horse fish around - I've sight-fished (and landed) 22" and 23" specs over green lights with it. It's also go-to for super-light bait rig, Mansfield mauler 4' leader and bare hook for tiny live shrimp (the smaller the better).
It has 4-lb Kamikaze copolymer (only 4-lb copolymer made anywhere).
