I’ve got 2 identical reels. One with 30lb braid one with 30lb mono.
Mono is more stretchy than Braid – You can feel alot more on braid due to no stretch.
Braid is smaller diameter than mono – Can get more braid on the reel
I dont find alot of difference in casting distance – although in theory braid should be slightly better
I find the mono gets damaged easier – especially if getting smashed by waves on shingle beaches
Braid is heaps more expensive than mono
I’ve got mates who have gone with braid on most of the reels. I just dont see that much of an advantage. Maybe it would be more noticeable if I was jigging or fishing deep water. But off the beach I find either of them is fine.
