Depends on your applications i guess.
I use 10# berkley big game for trolling using inline planer boards or for traditional big board fishing with releases.
When it comes to my BB rods, i run 20# Power Pro on those because its thin and gets my BB to the bottom with less line out because it is thinner in diameter and has less blow back. Braid is another good option for running cranks deep, as well as dipseys, mini disks or jets if you have to get them deep. If your not fishing overly deep, then the mono will work on the jets and mini disks as well.
