in mono i like mr Crappie in 8 lb test hi vis yellow.....but my fav is Power Pro "Slick" in 20 to 30 lb test in hi vis yellow..i fish brush and boat slips a lot and mono of any kind just gets frayed too easy where Braid just lasts all year and has zero stretch and much better sensitivity to detect even the lightest bite!
I agree with this comment about braid and would expand on it a bit...although I dont like hi-vis braid, (I prefer black) the strength/sensitivity of braid is necessary in a majority of my fishing outings. I like the Power Pro slick, as it is not hard on the rod guides... but also really like the Bonehead 12 for the same reasons...plus you can break it off if you need to for some reason. Also, I seldom use braid in clear water anymore, unless have no other option.
I have tried the Mr. Crappie hi vis in the past. I use spinning equipment for crappie, and my level of frustration with that line was considerable...It was ok for the first time or two after I spooled it; after that it was aggravating to say the least...seemed like I spent more time worrying with the line than fishing...so I would respool and drive on...anyway, that is my experience, and I would suggest there are many good mono, flouro and copoly lines available that will fit the bill, just try to determine what your use is going to be and what your needs are. Good luck and good fishing!
