I use 15# P-Line CXX in moss green color on my bait casting reels. It is considerably stronger than 20# Stren or Trilene. You can literally pull up stumps with the stuff. It's got some memory, which isn't a big problem with a bait casting reel, but it takes a real beast of a fish to break you off .... and then you have to thumb the spool to break it. This time of year I would not recommend spinning tackle or line lighter than 15# because your next bite could always be from a 10+ pound bass.
