For my dense cover punching, flipping, and pitching line, I use 65lb PP braid. Depending on the density of the cover I will use 1/2oz up 1.5oz Tungsten weight. As far as mono working? I am sure it will, it was the line of choice back in the day. Presently, there are several line choices that will get the job done a little better imho. I choose braid, because this type of fishing is so up close and personal, I prefer a line that has 0 shock absorption and allows me to remove fish out of cover quickly. Of course the type of rod and reel you are using play an important role in this as well.
