I fish with braided line all the time (20# Power Pro) and people always give me crap...."I can't believe you fish with that junk" or at the reel repair shop "you want me to take that junk off there and put some line on it?"
Last fall, I'd had enough heckling and trash-talking, so, I swapped out to monofilament. But I guess after fishing with the braided for so long, I just don't like the mono. I couldn't feel my lure at the end of the line, not like I can with braided. Mono just has way too much stretch and give for my liking. With braided, I can put a minnow on a bottom rig, and I can feel the minnow twitching. With mono, I'm lucky if I can feel the weight of the rig on the end of the line.
So, I ended up going back to braided line.
The drawback to braided is that because it has no stretch, you have to fish with a very loose drag, particularly when fishing for sea trout, which are notorious for having soft mouths. Also, you ain't just gonna tie a knot in the braided and pop it like you can with mono....if you want to cut this stuff, you better have your knife or scissors. Braided line will cut the hell out of you if you wrap it around any part of your hand with pressure applied, unlike mono, which is a lot more forgiving.
I hear people say "but that braided line will cut into your reel arbor...." Yeah, that's why you put some backing on it, by winding on some 20 pound mono, then doing a blood knot, and then putting on the 150 yards of power pro.
"But it will cut your guides"
Well, my fishing rods (except for my fly rods) are all cheap models, so, if they last long enough for an eye to be cut by the braided line.....it's served its purpose.
